Fort Nassau was the first Dutch settlement in North America, located beside the "North River" (the modern Hudson) within present-day Albany, New York, in the United States. The factorij was a small fortification which served as a trading post and warehouse.

Castle Island is a former island located in the city of Albany, Albany County, New York. Over the past 400 years, Castle Island has been referred to as Martin Gerritse's Island, Patroon's Island, Van Rensselaer Island, and—since the late 19th century--Westerlo Island. (Van Rensselaer Island is also the name of a former island opposite Albany in the city of Rensselaer.) The land known as Castle Island has been connected to the mainland and now forms a part of the Port of Albany.

Beverwijck ( BEV-ər-wik; Dutch: Beverwijck), often written using the pre-reform orthography Beverwyck, was a fur-trading community north of Fort Orange on the Hudson River within Rensselaerwyck in New Netherland that was renamed and developed as Albany, New York, after the English took control of the colony in 1664.

The Crailo State Historic Site (also known as Fort Crailo and Yankee Doodle House) is a historic, fortified brick manor house in Rensselaer, New York which was built in 1707. The word Crailo is derived from kraaien bos (Dutch for "crow's woods") and refers to Kiliaen van Rensselaer's estate in Huizen, Holland, which is also named "Crailo". Fort Crailo is listed on the National Register of Historic Places.

Aiken House is a historic home located in Rensselaer in Rensselaer County, New York. It was built about 1816 and is a 2+1⁄2-story, rectangular, brick townhouse dated to the Federal period. It has a 2+1⁄2-story rear wing. It features stepped gable sides. It was built by the founder of the City of Rensselaer, William Akin, and designed by noted Albany architect Philip Hooker (1766-1836).It was listed on the National Register of Historic Places in 1974.

The Pastures Historic District is a residential neighborhood located south of downtown Albany, New York, United States. Its 17 acres (6.9 ha) include all or part of a 13-block area. It was originally an area set aside as communal pasture by Albany's city council in the late 17th century and deeded to the Dutch Reformed Church. As the city began to grow following its designation as New York's state capital a century later, it was subdivided into building lots, some of which were developed with small rowhouses. Many open areas remain today, and the houses have not been significantly altered. In 1972 the city designated it as a historic district and it was listed on the National Register of Historic Places. All but two buildings in the district are considered historic. One of Albany's busiest neighborhoods in the 19th century, the area fell into decline during the third quarter of the 20th as citizens left the city for the suburbs. Instead of the wholesale demolition of that era's urban renewal programs, the city government attempted to preserve and revitalize the area, evacuating the residents for years and demolishing some properties, a move that has been criticized as destroying the neighborhood as a standard urban renewal project would have. A recent mortgage fraud scandal has affected the neighborhood also, but it has once again become a diverse, fully occupied neighborhood.

The South End–Groesbeckville Historic District is located in part of the neighborhood of that name in Albany, New York, United States. It is a 26-block, 57-acre (23 ha) area south of the Mansion and Pastures neighborhoods with a mix of residential and commercial properties. In 1984 it was recognized as a historic district and listed on the National Register of Historic Places. For several decades after the city's founding in the late 17th century, the South End was undeveloped. In 1761 General Philip Schuyler built his house there. Today it is a National Historic Landmark, the oldest building in the district and the only contributing property in the district individually listed on the National Register. As the city grew following the opening of the Erie Canal in the early 19th century, development did not reach the South End immediately, save for an early toll road, now South Pearl Street (part of New York State Route 32) built in the first years of the 19th century, which later became the backbone of the South End. Planned streets for the neighborhood were included in Albany's grid pattern as early as 1818. They were built in the middle of the century, and by the 1870s the district had begun growing rapidly, fueled by German immigrants, a group still closely associated with the South End and the first of several waves of immigrants to leave their mark on it. Irish Americans would also consider it theirs even as they dispersed to other parts of the city, and one native of the district, Daniel P. O'Connell, grew up to become boss of the city's Democratic political machine well into the 20th century, using a now-demolished building in the district as his headquarters.The district is the only large area of Albany predating the 20th century where houses were largely built by the future occupants one at a time, rather than in large sets of speculative houses by developers (as one later historian put it "[it] wasn't planned, it just grew"), resulting in great architectural variety. The hamlet of Groesbeckville in the neighboring Town of Bethlehem, which at the time was just to the south, grew along similar lines and was soon absorbed into the city, the first expansion of Albany's southern boundary. The new neighborhood became the first home for many of the immigrant groups that would populate the city into the 20th century, including African Americans dislocated by urban renewal elsewhere in the city. Today the district remains largely intact (only 13 of the district's 520 buildings, or 2.5 percent, were, at the time of listing, non-contributing) but struggles with the effects of urban decay. A neighborhood association has worked with the city to develop a revitalization plan.

Schuyler Mansion is a historic house at 32 Catherine Street in Albany, New York. The brick mansion is now a museum and an official National Historic Landmark. It was constructed from 1761 to 1765 for Philip Schuyler, later a general in the Continental Army and early U.S. Senator, who resided there from 1763 until his death in 1804. It was declared a National Historic Landmark on December 24, 1967. It is also a contributing property to the South End–Groesbeckville Historic District, listed on the National Register of Historic Places in 1984.

USS Slater (DE-766) is a Cannon-class destroyer escort that served in the United States Navy and later in the Hellenic (Greek) Navy. Following service during World War II, the ship was transferred to Greece and renamed Aetos. Decommissioned in 1991, the destroyer escort was returned to the United States. USS Slater is now a museum ship on the Hudson River in Albany, New York, the only one of its kind afloat in the United States. As of 2020, fewer than 12 destroyer escorts survive, with Slater the only one in its wartime configuration. Slater was designated a National Historic Landmark on 2 March 2012.USS Slater was struck by the Hudson River touring ship Dutch Apple on 10 September 2019. A mechanical issue aboard Dutch Apple was to blame for the collision.

W. P. Irwin Bank Building is a historic bank building located at Rensselaer in Rensselaer County, New York. It was originally built in 1873 and is a 2-story, rectangular flat-roofed, masonry structure on a stone foundation. A 1+1⁄2-story, four-bay flat-roofed brick rear wing was added in 1905. The building exhibits a number of Gothic Revival details.It was listed on the National Register of Historic Places in 2007.

Fort Orange (Dutch: Fort Oranje) was the first permanent Dutch settlement in New Netherland; the present-day city of Albany, New York developed at this site. It was built in 1624 as a replacement for Fort Nassau, which had been built on nearby Castle Island and served as a trading post until 1617 or 1618, when it was abandoned due to frequent flooding. Both forts were named in honor of the Dutch House of Orange-Nassau. Due to a dispute between the Director-General of New Netherland and the patroonship of Rensselaerswyck regarding jurisdiction over the fort and the surrounding community, the fort and community became an independent municipality, paving the way for the future city of Albany. After the English reconquered the region they soon abandoned Fort Orange (renamed Fort Albany) in favor of a new fort: Fort Frederick, constructed in 1676.

The Mansion Historic District, sometimes referred to as Mansion Hill, is located south of Empire State Plaza in Albany, New York, United States. It takes its name from the nearby New York State Executive Mansion, which overlooks it. It is a 45-acre (18 ha), 16-block area with almost 500 buildings. Many of them are rowhouses and townhouses built in the middle and late 19th century that remain mostly intact today. It was first developed in the early 19th century as a small group of estates for wealthy citizens. Later it was subdivided, becoming the first home for several waves of immigrant groups, most notably Italian Americans. In the mid-20th century it began to decline when the construction of Empire State Plaza cut it off from downtown and adversely impacted the neighborhood. A local neighborhood association was formed during this period and has been credited with helping the Mansion neighborhood recover and become a desirable place to live in the early 21st century. In 1982 it was designated a historic district by the city's Historic Resources Commission and listed on the National Register of Historic Places.
