The Winslow Chemical Laboratory was a laboratory of the Rensselaer Polytechnic Institute campus in Troy, New York, United States, which finished construction in 1866. It is named in honor of the 5th President of RPI, John F. Winslow, who donated half of the construction cost. The building is brick with stone trimmings and was originally constructed with butternut, chestnut and black walnut. The whole building was fitted for complete courses in general and analytical chemistry. The design and construction was overseen by Professor Henry B. Nason, head of the department of chemistry at the Institute. The lower story contained the metallurgical laboratory and second story contained the chemical laboratory, store rooms and work rooms. The laboratory could accommodate about 40 students. The third story contained a lecture room, a private study, the library and a recitation room. The library of chemical books was established by a donation of several sets of journals and a gift of three hundred dollars from John F. Winslow.The laboratory was damaged by a fire in the upper story in 1884 and was rebuilt and enlarged in 1885. The building was again damaged by fire in 1904. It was used as a laboratory until 1907 and then converted into a shop. The building, falling into disrepair, was boarded up in the early 1970s and targeted for demolition. It was added to the National Register of Historic Places on November 4, 1990. As an effort to save the building, it was agreed with the city of Troy that the building would be leased to house a new children's science museum called the Junior Museum. The Junior Museum refurbished the Winslow building and opened its doors in 2000. Since then, the Junior Museum has moved to the Rensselaer Technology Park, and currently the Winslow Building is home to many research groups affiliated to Cognitive Science and Computer science departments of Rensselaer, namely, Rensselaer AI and Reasoning Lab, the Social and Behavioral Research Laboratory, the Tetherless World Constellation (since 2007) etc.

Union Station was the main passenger railroad station of Troy, New York until it went out of service in 1958. A Beaux-Arts building, designed by Reed & Stem and completed ca. 1903, it served the New York Central Railroad (NYC), the Boston and Maine Railroad (B&M) and the Delaware and Hudson Railroad (D&H). This was the fourth union station in Troy. The tracks approaching the station were but feet away from homes. It stretched from Broadway to Fulton streets, on the block east of Union Street.The New York Central use, by mid-20th Century, was mainly for conveying trains from the territory to other routes, carried by other companies. Thus, the D&H's Laurentian and Montreal Limited moved from NYC tracks to D&H tracks when leaving north from the station, toward their Montreal destination. Until 1953, the Rutland Railroad ran the Green Mountain Flyer and the Mount Royal from New York City, then moved at Troy onto B&M tracks, for eventual completion of their trip on Rutland Railroad track (also bound for Montreal).The Boston & Maine ran the Minute Man from Troy Union Station to Boston's North Station. This train passed through the famed Hoosac Tunnel near North Adams and specialized in serving northwestern and north-central Massachusetts. The cutting of the Minute Man back to Greenfield, Massachusetts in January 1958 precipitated the closure of the station that year. The station was demolished later that year.

The U.S. Post Office in Troy, New York, United States, is located at 400 Broadway, on the corners of Fourth (US 4) and William Streets, the tenth location it has occupied in the city's history. It serves the ZIP Codes 12179 through 12182, which cover different sections of the city. In 1989 it was added to the National Register of Historic Places, and it is also a contributing property to the Central Troy Historic District, which covers much of the city's downtown commercial area. It was built during the Great Depression as part of a massive statewide public works initiative to stimulate the economy and provide jobs. Louis Simon, supervising architect for the Treasury Department, used a stripped-down Classical Revival style for the post office, which replaced a much-beloved older one. Painter Waldo Peirce added two murals to the building's lobby in 1938, making Troy's one of only three post offices in the U.S. with his artwork.

Proctor's Theater is located on Fourth Street (northbound US 4) in Troy, New York, United States. It was listed on the National Register of Historic Places in 1979, and is a contributing property to the Central Troy Historic District, added to the Register in 1986. It was built in 1914 for vaudeville performances by Capital District entrepreneur Frederick Freeman Proctor, who also built another theater with his name in nearby Schenectady. Its double-balcony auditorium made it easily adaptable for showing motion pictures when that entertainment came into fashion soon after it opened. The building is credited to architect Arland W. Johnson.In the late 1970s it closed. Since then it has been through several owners, including Rensselaer Polytechnic Institute (RPI), which have had various plans, including renovating it into office space or reusing it as a theater. In 2014, it was announced that Columbia Development would be renovating the building for the Rensselaer County Chamber of Commerce.As of September 2018, the building has been repurposed into a modern office space behind the preserved façade. Current tenants include the Rensselaer County Chamber of Commerce, Rensselaer Polytechnic Institute and Christopher Brian Salon.

It borders the Rensselaer Polytechnic Institute campus to the East and South. The church was founded by Mary Warren in the early 1840s. Under the direction of Mary Warren's son, Nathan B. Warren, the church nave was built from designs by Alexander Jackson Davis in 1844. The chancel addition, by Richard Upjohn, was completed in late 1848 and dedicated in January, 1849. In 1846, the Church instituted one of the first choirs at an Episcopal church in the United States. During the full choral service, the psalter, creed and responses of the English Cathedral Service are chanted by the choir while the officiant intones his part. In 1863, the Mary Warren Free Institute was built adjoining the church to the south in order to further religious and musical instruction. The Institute still exists to this day.
