The Adrian building was named after Brother Adrian August who was a Chemistry and Music professor at Marist College. This was one of the buildings constructed almost exclusively by the Marist Brothers, and was completed in 1957. It was a small one-story building located across the road from Donnelly Hall. Its first use was as a place where students could meet with guests. Day students used it as a place to study, eat lunch, and relax. It contained a sitting room, an entertainment audio center, and an office for Brother Nilus Donnelly. In later years it served the needs of the Alumni office and the Marist Poll. It was removed in 2000 for the construction of the James A. Cannavino Library. The commuter lounge was moved to the Student Center and the Alumni office and Marist Poll were both relocated to the new Fontaine Hall.

In the mid-1800s, Edward Bech, founder of the Tuckerman and Bech Iron Comany, purchased Hickory Grove, a 65 acre farm along the Hudson River, which he then renamed "Rosenlund." Although the main house was never built, the three service buildings still remain in the heart of the Marist campus: Kieran Gatehouse, Greystone Carriage house, and St. Peter's. In 1908, the Marist Brothers purchased the Edward Bech estate, by then a 110-acre plot of land, to expand the Hermitage that had been purchased in 1905. This plot of land is the current location of Marist College, west of Route 9 and as far North as Fern Tor and St. Ann's Hermitage. The Beck Place Parking Lot is located across from the Marist Campus and is used as a lot for commuters, visitors, and an over-flow lot for underclassmen with cars.

Benoit & Gregory Houses were erected in 1968 as residences for the Marist Brothers living on campus. Both houses were constructed identically: the main section, octagonal in design, contains sixteen bedrooms allowing for Benoit and Gregory to house thirty-two students each. Benoit House honors the memory of Brother Fancis Xavier Benoit who taught at Marist for nineteen years, while serving also as a Director of Construction for the Marist Brothers. Gregory House was named in memory of Brother Joseph Gregory Marchessault who was chairman of the Physics Department at Marist until the time of his death in 1969.

The Byrne House was built in the early days of the expansion of Marist College in 1960. It was built as a residence for the Dominicas Fathers, who were at that time chaplains at the College. After this application, it was used as a location for the campus nurse and counseling activities. At the present time, it is being used as the school ministry and student counseling center. It is located in the back of Champagnat Hall, overlooking the Hudson.

Champagnat Hall, the tallest building on campus, was constructed in 1964. Named to honor the memory of Marcellin Champagnat, the French priest who founded the Marist Brothers in 1817, the nine-story residence hall houses over 400 first-year students. Residents have dramatic views of the Hudson River Valley, north and south. Special Services offices are located on the first floor. Champagnat was renovated in 2003 and is one of two residence halls with immediate access to the Student Center.

The Donnelly building was built on the land between the Kieran Gate House and the Bech family home. The Bech family home served as a Novitiate for the Marist Brothers as well as a residence for the Brothers who volunteered to help build Donnelly Hall.

The Dyson Center was completed in 1990 and is named in honor of the late businessman and philanthropist Charles H. Dyson and his late wife Margaret. The three-story Dyson Center houses the School of Management, which recently added online M.P.A. and M.B.A. degree programs to its offerings. Also located here are the School of Social and Behavioral Sciences, the Office of Graduate and Continuing Education, the Bureau of Economic Research, and corporate education and training programs. The 53,000 square-foot Dyson Center holds 23 classrooms and 55 faculty offices as well as seminar rooms and a computer lab. The building’s coffee shop and its three-story atriums are popular areas for students to meet and relax between classes.

Fern Tor is the 13 acre estate acquired by Marist College in 1997. The estate, at the campus's northern boundary, is a quiet retreat rich with trees, wild flowers, herbs, shrubs, wildlife and several ecological habitats. It is graced by a Hudson River view and 800 feet of shoreline. The land remained undeveloped until 1861 when Thomas Newbold purchased it for the site of his family's home. By the 1880s Newbold had constructed a mansion with a southern vista of the Hudson River, a summerhouse, formal gardens, greenhouses, a man-made pond, and a carriage house. Frederick Newbold inherited the estate from his father, and Frederick named the property Fern Tor after its ferns and rocky hills. The next generation of Newbolds sold the property to the Way family, who transformed the carriage house into their home and eventually sold the parcel to Marist. The foundations are all that remain of the mansion, which marked the highest point on the Marist campus.

Fontaine Hall was named after Brother Paul Ambrose Fontaine, FMS. President Emeritus and a Life Trustee of the College, Brother Paul played an integral role in shaping Marist during its early years. The original Fontaine Hall served as a study hall and dining room for the student Brothers at Marist College, although its purpose varied as the College expanded. It was constructed by the Marist Brothers in 1956, and later an addition was made to serve as a dormitory for the student Brothers. Subsequently, the addition was used as an office building for the Humanities Division. The original part of the building served as a library until shortly before the Cannavino Library was built. With the decision to construct the Cannavino Library on the same site, the original Fontaine Hall was razed and new Fontaine Hall was built to house the offices of the School of Liberal Arts on the northern end of campus.

The Foy Townhouses were built in 1982 and are named after President Emeritus and Life Trustee, Dr. Linus Richard Foy. Dr. Foy was named President of Marist College in 1958 and became, at the age of 28, the youngest college president in the United States. He served as President of Marist College from 1958 to 1979, and made countless contributions to the continued development and success of the College.

The Gartland Commons were built in 1985. The fifty-two unit apartments accommodate 306 students in four buildings. Overlooking the Hudson River, each apartment provides a living room, bathroom, three bedrooms, and a fully equipped kitchen with nearby recreational facilities.

Greystone is one of three Marist buildings that were part of the Rosenlund Estate purchased by the Marist Brothers in 1908. Listed on the state and national Registers of Historic Places, Greystone dates to around 1865 when it was built as a carriage house; a hayloft occupied the top floor, carriages and horse the middle floor, and a blacksmith shop occupied the lowest level. Through remodeling in 1909, 1928, and 1964, the building has served as a dormitory, classrooms, science labs, and a library. Since 1964 the building has housed the office of the College President. Greystone closely resembled the style of St. Peter’s and the Kieran Gatehouse when it was first constructed. When the College was first established and was still known as Marian College, the renovated carriage house was surrounded by wooden structures. The carriage house was nicknamed “Greystone” by the Marist Brothers on campus because of its distinctive stonewalls. The name was made official in 1929 when the junior college was established.

The Library is named after James A. Cannavino, a long-time Trustee and former Chairman of the Board. Developed as part of the worldwide Digital Library Initiative launched by the IBM Corporation to facilitate anytime, anywhere access to books, periodicals, works of art, film, music, and rare manuscripts, the Cannavino Library is a model for academic libraries of the new century. Overlooking the campus green and the Hudson River, this 83,000-square-foot facility is a state-of-the-art electronic teaching and service center at the hub of an electronic network linking all parts of the Marist campus to libraries and databases throughout the world. In addition to providing a number of spacious study areas and attractive quiet rooms for research, conferences, and collaborative work, the Library also houses the Archives and Special Collections rooms, an office overlooking the campus for the College President, and a multi-media language center on the third floor. A small café on the main floor of the Library also provides the students with a gathering place where they can have a bite to eat, drink coffee, and not have to worry quite as much about the level of their voices.

The McCann Center is home to Marist College’s intercollegiate, intramural, and recreational athletics programs. The original 57,200 square-foot McCann Center, including a field house, Olympic swimming pool, dance studio, and weight room, was built in 1977 with funding from the James J. McCann Foundation. The McCann Foundation again gave its support to construct a 20,000 square-foot addition that opened in 1997. The expansion features an 11,000 square-foot multipurpose gymnasium, a 4,300 square-foot weight training area, a 4,000 square-foot cardiovascular area, a student lounge and locker rooms, and the electronic Pepsi Athletic Hall of Fame, a multimedia room and computer lab honoring athletes and teams from Marist College and surrounding Dutchess County.

Listed on the state and national Registers of Historic Places, the Kieran Gatehouse dates to 1865 and was a gatehouse on the estate purchased by the Marist Brothers in 1908. This quaint cottage has remained in constant use, first as a headquarters for the Poughkeepsie Province of the Marist Brothers and then as office space and a private residence. Brother Paul Ambrose Fontaine used the Gatehouse as his office during his tenure as President of the College. The Gatehouse was renamed the Kieran Gatehouse in October 1990 when it was dedicated to the late Brother Kieran Thomas Brennan. Not only was Brother Brennan a long-time trustee of Marist College, but he was also the director of student Brothers from 1954 to 1964.

Professor Daniel Kirk, former Chairman of the Psychology Department, built the Kirk House in 1976 for his private residence. Dr. Kirk generously willed his home to Marist College. It became the residence of the Marist College Catholic Chaplain and continues to be used for this purpose today.

The Construction for Leo Hall was funded with a federal government loan, and the dorm opened in 1963. When women were invited to live on campus in 1969 they first occupied the sixth floor of Leo Hall. Currently used as a coed residence for freshman, it is dedicated to the memory of Brother Leo Brouiletter, Provincial of the Marist Brothers, from 1921-1930. Brother Leo was responsible for securing the original charter for the Marist Normal Training School in 1929.

Leonidoff Field, Marist College's first major athletic field, is an outdoor stadium that provides seating for over 3,000 spectators for home soccer, lacrosse, and football games. The athletic field is named after Dr. Aleski A. Leonidoff and was dedicated in 1968. Raised and educated in Russia, Aleski Leonidoff developed a relationship with Marist College through Jack Gartland. During his tenure as a physician at St. Francis Hospital, Dr. Leonidoff donated money to the College for the construction of the Leonidoff Athletic Field. Dr. Leonidoff also donated funds to suport a scholarship for students specializing in science pre-medical studies.

The Lowell Thomas Communications Center houses the academic disciplines of communications and computer science. Features of the center, which opened in 1987, include the Charles and Cornelia Murray Journalism Room, which offers everything students need to write, edit, and present printed news. The building holds five classrooms with computer and television access, two television studios, two radio broadcast production rooms, and film processing areas. These facilities, along with adjacent faculty offices, meet the demands of almost 700 undergraduate students annually who concentrate in communications, Marist’s largest major. The building is named after Lowell Thomas, who was a pioneer in the field of communications, an author, and a world traveler.

The present Marian building was built as a gym in 1948. This was the first large building put up by the Marist Brothers on what is now the Marist College campus. Brother Francis Xavier, who at the time taught Philosophy and Psychology at the College, supervised the work. "Frank," as he was known, was a man of all trades and as much a contractor as he was a professor.

The Martin boathouse was built in 1963 in memory of William Martin who was the chairman for the fund drive to build the boathouse. The boathouse was built to house the rowing and sailing equipment of Marist College. There are two ramps leading directly from the boathouse into the Hudson, which are used to launch the crew boats and the sailboats. Initially, Marist competed in sailing and crew. Blue Jays were used in sailing competition and pleasure sailing for the students and faculty of Marist College. These were 13-foot wooden sloop rigged boats. In 1966 the Blue Jays were replaced by Barnegates, which were 19-foot fiberglass sloops. These could carry up to six people, but were also used in competition with a crew of two. Smaller boats later replaced the Barnegates. Marist crew has been very active in the competitive sports world since the early 1960s.

The New Townhouses were built in 1993 and accommodate 144 junior and senior students in six buildings overlooking the Hudson River. Each building has a number of units with space for eight students, including living, dining, and lounging areas. The complex has its own central laundry facility. Some units are avaliable to accommodate qualified, physical handicapped students.

When the chapel was built in 1953, its circular design was one of the first for a Catholic church in the United States. The altar dominates the center with the congregation intimately flowing completely around it. It was not until the Second Vatican Council in 1965 that churches began to move their altars into a similar relationship with their parishioners.

In 1905, with the help of Father H. Havens Richards, SJ, St. Ann's Hermitage was the first building in Poughkeepsie purchased by the Marist Brothers. It had previously been the homestead of the Mac Pherson family. Brother Zepheriny, FMS, purchased this estate from its owner, Mrs. Goodwin of New York City. The property, which was at the time a mile outside of the City of Poughkeepsie, included some 35 acres north of the Waterworks Road and sold for $9,000.00. This building was used as a Provincial House until the early fifties. In addition to the provincial administration, it also housed the Scholastics usually numbering around 75 students. There was a chapel with a pipe organ where a Jesuit from St. Andrew’s celebrated daily mass. Also living in this building was a community consisting of the provincial tailors who made the cassocks for all the Brothers of the province. Others living in this building included a director, a cook, several young brothers to help in the tailor shop, in the garden, and with the laundry, a farmer who took care of the cows and pigs, and two farmers who took care of an extensive vegetable garden and a green house which was located across from St. Peter’s. The infirmary, which had from 5 to 13 Brothers who needed medical attention, was also located in this building.

Built circa 1865, St. Peter’s originally housed the Rosenlund Estate’s gardener and his family. The Marist Brothers purchased the estate in 1908 and until 1969, St. Peter’s served as a residence for the Marist Brothers. Currently it houses administrative offices. It is named St. Peter’s because the Brothers who lived there from 1909 until 1936 taught in St. Peter’s school in Poughkeepsie.

In March of 1961 Brother Linus Richard Foy, President of Marist College, received confirmation for a government loan for a dormitory that would accommodate 120 students and three faculty advisors. This was the first building on the property that was not constructed by the Marist Brothers since the property was purchased in 1908. Sheahan Hall was one of the first dormitories where women lived when the College became a coeducational institution in 1969. It currently houses freshman students and is named in memory of Monsignor J. F. Sheahan, pastor of St. Peter’s Church in Poughkeepsie. Monsignor Sheahan used his influence to help the Brothers purchase the Bech Estate in 1908. Today this property forms the entire Marist College campus south of the Waterworks Road (the main entrance to the campus).

The Marist College Art Gallery is a 3,200 square-foot space located in the Steel Plant Studios along with the Fine Arts Program. It was purchased in 1997 to house the college library temporarily while the new James A. Cannavino Library was under construction. After the library was built, the old industrial site was renovated to become the Steel Plant Studios. The building houses several studios including: a 2D/Graphic Desin Studio, Drawing and Painting Studios, a 3D/Sculpture Studio, a Special Processes & Techniques Studio, a fully equipped Digital Media Studio, and a new 2,500 square-foot Art Gallery. The Art Gallery retains the industrial look of the former steel plant with concrete floors and exposed 15-foot ceilings. The exhibition program focuses primarily on contemporary regional artists working in all fine arts media.

The Student Center serves as the focal point of the College, bringing together all members of the Marist Community.

The Talmadge Court Apartments were purchased in 1996 and are located about one-quarter of a mile from the south entrance of Marist College. The complex contains 11 apartments, consisting of nine two-bedroom units and two one-bedroom units. Profesional housing staff live on-site with the students.

West Cedar is divided into two sections across Route 9 on West Cedar Street. The two sections, Lower (labled O-S and completed in 1998) and Upper (labeled T-Y and completed in 2000) together accommodate 468 students in twelve buildings. Each building has a number of units with space for either eight or eleven students, including living, dining, and lounging areas. The complex has its own central laundry facility. The students in West Cedar enjoy a community-like life just off campus to experience the independance of being a little farther away, and yet close enough to enjoy the comforts of Marist security.
