24 Colonial forts in New York (state)

Fort Amsterdam was a fort on the southern tip of Manhattan at the confluence of the Hudson and East rivers. It was the administrative headquarters for the Dutch and then English/British rule of the colony of New Netherland and subsequently the Province of New York from 1625 or 1626, until being torn down in 1790 after the American Revolution. It was the nucleus of the settlement in the area that became New Amsterdam and eventually New York City.

Fort Brewerton is a historic fort site located at Brewerton in Oswego County, New York. It is the site of a fort that originally was in the form of an eight-pointed star with sixteen 30-foot (9.1 m) faces surrounded by a 10-foot (3.0 m) moat. The 480-foot-long (150 m) parapet had earth walls 5 feet (1.5 m) high from which projected log palisades. Within the parapet were four log blockhouses, smaller buildings for munitions and supplies, and wells. It was erected in 1759 to defend the passage from Albany to the port of Oswego.

Fort Bull was a fort located at the Oneida Carry in British North America during the French and Indian War.

Fort Carillon, the precursor of Fort Ticonderoga, was constructed by Pierre de Rigaud de Vaudreuil, Governor of Canada, to protect Lake Champlain from a British invasion. Situated on the lake some 15 miles (24 km) south of Fort Saint Frédéric, it was built to prevent an attack on Canada and slow the advance of the enemy long enough for reinforcements to arrive.

Fort Crown Point was a British fort built by the combined efforts of both British and provincial troops in North America in 1759 at a narrows on Lake Champlain on what later became the border between New York and Vermont. Erected to secure the region against the French, the fort is in upstate New York near the town of Crown Point and was the largest earthen fortress built in the United States. The fort's ruins, a National Historic Landmark, are now administered as part of Crown Point State Historic Site.

Fort Denonville was a French fort built in 1688 at the current site of Fort Niagara. It replaced Fort Conti which had been built on the site in 1679 and had burned later that year.

Fort Frederick was a fort in Albany, New York from 1676–1789. Sitting atop State Street Hill it replaced the earlier decaying Fort Orange along the Hudson River. The fort was named for Frederick Louis, Prince of Wales, son of King George II. The fort was referred to as Fort Albany in the 1936 novel Drums Along the Mohawk. Several historical markers have been placed west of the location of the fort.

The Fort de La Présentation, a mission fort, was built in 1749 and so named by the French Sulpician priest, Abbé Picquet. It was also sometimes known as Fort La Galette. It was built at the confluence of the Oswegatchie River and the St Lawrence River in present-day New York. The French wanted to strengthen their alliance with the powerful Iroquois, as well as convert them to Catholicism. With increasing tensions with Great Britain, they were concerned about their thinly populated Canadian colony. By 1755 the settlement included 3,000 Iroquois residents loyal to France, in part because of the fur trade, as well as their hostility to encroachment by British colonists in their other territories. By comparison, Montréal had only 4,000 residents.

Fort Lévis, a fortification on the St. Lawrence River, was built in 1759 by the French. They had decided that Fort de La Présentation was insufficient to defend their St. Lawrence River colonies against the British. Named for François Gaston de Lévis, Duc de Lévis, the fort was constructed on Isle Royale, 3 miles (4.8 km) downstream from the other fort. The fort surrendered after intense bombardment in August 1760 to the British and was renamed Fort William Augustus. The fort was abandoned in 1766. During the construction of the Saint Lawrence Seaway, the remains of the fort were destroyed and submerged beneath the waters of the river.

Fort Niagara is a fortification originally built to protect the interests of New France in North America. It is located near Youngstown, New York, on the eastern bank of the Niagara River at its mouth, on Lake Ontario.

Fort Ontario is an American historic fort situated by the City of Oswego in Oswego County, New York. It is owned by the state of New York and operated as a museum known as Fort Ontario State Historic Site.

Fort Orange 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 in favor of a new fort: Fort Frederick, constructed in 1676.

Fort Oswego was an 18th-century trading post in the Great Lakes region in North America, which became the site of a battle between French and British forces in 1756 during the French and Indian War. The fort was established in 1727 on the orders of New York governor William Burnet, adjacent to a 1722 blockhouse that had originally been a way station for French traders. The log palisade fort established a British presence on the Great Lakes.

It was located in modern New York State across the lake from modern Vermont at the town of Crown Point, New York.

Fort Stanwix was a colonial fortress whose construction commenced on August 26, 1758, under the direction of British General John Stanwix, at the location of present-day Rome, New York, but was not completed until about 1762.

Fort Stanwix National Monument, a reconstructed structure built by the National Park Service, now occupies the site.

Fort Ticonderoga, formerly Fort Carillon, is a large 18th-century star fort built by the French at a narrows near the south end of Lake Champlain, in northern New York, in the United States. It was constructed by Canadian-born French military engineer Michel Chartier de Lotbinière, Marquis de Lotbinière between October 1755 and 1757, during the action in the "North American theater" of the Seven Years' War, often referred to in the US as the French and Indian War. The fort was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played an important role during the Revolutionary War.

Fort Wadsworth is a former United States military installation on Staten Island in New York City, situated on The Narrows which divide New York Bay into Upper and Lower halves, a natural point for defense of the Upper Bay and Manhattan beyond. Prior to closing in 1994 it claimed to be the longest continually garrisoned military installation in the United States. It comprises several fortifications, including Fort Tompkins and Battery Weed and was given its present name in 1865 to honor Brigadier General James Wadsworth, who had been killed in the Battle of the Wilderness during the Civil War. Fort Wadsworth is now part of the Staten Island Unit of Gateway National Recreation Area, maintained by the National Park Service.

Wall Street is an eight-block-long street in the Financial District of Lower Manhattan in New York City. It runs between Broadway in the west to South Street and the East River in the east.

Fort William Henry was a British fort at the southern end of Lake George, in the province of New York. The fort's construction was ordered by Sir William Johnson in September 1755, during the French and Indian War, as a staging ground for attacks against the French position at Fort St. Frédéric. It was part of a chain of British and French forts along the important inland waterway from New York City to Montreal, and occupied a key forward location on the frontier between New York and New France. In 1757, the French general Louis-Joseph de Montcalm conducted a successful siege that forced the British to surrender. The Huron warriors who accompanied the French army subsequently killed many of the British prisoners. The siege and massacre were famously portrayed in James Fenimore Cooper's novel The Last of the Mohicans.
