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.

The Fire Alarm, Telegraph and Police Signaling Building, usually referred to just as the Signaling Building, is located on State Street in Troy, New York, United States. It is currently used as storage space by Rensselaer County. It was built to implement a new combined fire and police "silent alarm" system in the early 1920s, using telephone wires instead of human bell-ringers. This represented the last step in Troy's efforts to prevent the devastating fires of the 19th century from destroying so much of the city again. It continued to be used for that purpose until 1968, and in 2003 it was listed on the National Register of Historic Places.

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.

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.

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.

The Church of the Holy Cross is a church in Troy, New York, United States. It was added to the National Register of Historic Places in New York in 1973. 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.

The Northern River Street Historic District is located along River Street (southbound US 4 at that point) north of Federal Street, one block east of the Green Island Bridge, in Troy, New York, United States. It was added to the National Register of Historic Places in 1988, as the Northern River Street District, to distinguish it from Troy's previously existing River Street Historic District, which had been one of five superseded by the Central Troy Historic District to the south two years earlier. Its two acres (8,000 m²) include 13 brick industrial and commercial buildings erected from the mid-19th to early 20th centuries. They were cut off from the rest of downtown due to the construction of the Rensselaer and Saratoga Railroad, and as a result became a production center for the city's major industries, primarily textiles. When those industries declined in the mid-20th century, they were further isolated from the city's center by expansion of Federal Street to provide access to the bridge, and various urban renewal efforts. As a result, they have not seen much redevelopment and remain mostly intact.

The National State Bank Building is located on River Street in Troy, New York, United States, at its junction with Fulton and Third (southbound US 4) streets. It was listed on the National Register of Historic Places in 1970, one of the earliest buildings in the city so recognized. Since 1986 it has been a contributing property to the Central Troy Historic District. It was built in 1904, on the site of a public market that had burned down the year before, by local architects M. F. Cummings & Son in the Beaux Arts architectural style. Five stories high, three bays wide by nine deep, its fenestration is similar to the larger Ilium Building a block to the east. The first story is faced in rusticated stone, the second through fifth in light gold brick with stone and terra cotta trim, and with carved stone panels beneath the third and fourth floor windows. These three distinct zones, along with the building's steel frame construction and use of an elevator inside, show the influence of early skyscraper design.
