Following the conquest of New Netherland in 1664, the territory that would later become New York State was ceded to the English. To maintain peace in Albany, Fort Frederick was constructed in 1676 to replace the then decaying Fort Orange. Fort Frederick, also known as Fort Albany in the 1936 novel, Drums Along the Mohawk, was named for the Prince of Wales, Frederick Louis. Strangely, the prince was not born until 1707, decades after the initial construction. Submitted by Cliff Lamere, Albany, NY: "I have only heard of two dates for dimantling the fort; 1784 which is before the Common Council decision to tear it down, and 1789...We know that the land on which the fort rested was deeded to St. Peter's Episcopal Church in 1790"

Fort Alden was constructed in 1778, in Cherry Valley, Ostego County, New York, and remained intact for only two years during the Revolutionary War.

The fortress was besieged a second time in 1780 and was subsequently destroyed. Notes: - A previous stockade on the site existed and was destroyed in the French and Indian War. It was replaced by Fort Campbell, named for Commander of Continental troops there. - Fort Alden possibly hosted two blockhouses. -First attack took place on November 11th, 1778 -Second attack took place in April of 1780 - The site is now marked by the Cherry Valley Cemetery.

The Amersfoort Blockhouse was a Dutch fortification founded in 1630 and decommissioned in 1664. It was located in the flatlands of Brooklyn, in Kings County, New York. It is likely named for the Dutch city of Amersfoort, founded in 1259.

Fort Crown Point was constructed in 1759 adjacent to Lake Champlain, in Northern New York, on the border with what would later become Vermont. The fort is often incorrectly referred to as “Fort Amherst”, as the facility was constructed under the command of Sir Jeffery Amherst of England. However, this name was never used until far after the fort was abandoned in 1780. The best-preserved remains of the fort are its stone barracks. Fort Crown Point was designated as a National Historic Landmark in 1968. The fort was also visited by various Founding Fathers, including Benjamin Franklin, George Washington, Thomas Jefferson, and James Madison.

Fort Amherst, initially called “Fort Miller”, was constructed in 1759 by the British just north of Glenn Falls, and close to what is now Lake George in Warren County, New York. It was demolished in 1760 and rebuilt fifteen years later by American soldiers just a year prior to the Revolutionary War. In 1777, Hessians, German soldiers who fought on the side of the British during the Revolution, occupied the fort. In 1780, Fort Amherst met its end after being brought to the torch by British forces. Notes: - The fort was located at the halfway point between Fort Edward and Fort William Henry/Fort George. - The fort was once a fortified camp between 1757 and 1758. - Also near this site was a stockaded enclosure known as Seven-mile post, or Halfway Brook Post, from 1755 to 1776, and a stockaded Garrison in 1758.

Fort Amsterdam was constructed by the Dutch West India Company in 1626 on the southern end of the island of Manhattan. It served as an administrative hub for the Dutch, specifically the Dutch West India Company, and later fell under control of the British after the conquest of New Netherland in 1664.

The fort was involved in many famous battles and wars such as the Battle of Long Island, the Second and Third Anglo-Dutch Wars, and the American Revolution.

During the construction, the fortification was under the supervision of Colonel Tadeusz Kościuszko. The fort was built near what is now West Point, in Orange County, New York.

Atlas Sites, 1961, a 12-missile Atlas F ICBM squadron (the 556th Strategic Missile Squadron) became operational 1 October 1961 at Plattsburgh AFB, NY,. The Atlas Fs were removed from alert on 25 June 1965. Ten of these 12 sites are in New York State, the other two in Vermont. The New York sites were at (1) Champlain, (4) Willsboro, (5) Lewis, (6) Au Sable Forks, (7) Riverview, (8) Redford, (9) Dannemora, (10) Brainardsville, (11) Ellenburg Depot, and (12) Mooers. The first Atlas F missile system was built in 1960, after a short operational period, was decommissioned in 1965. These sites were the first of the "super hardened"; missile silos, built to withstand a 200 pound per square inch blast. There is one reported in Saranac Lake area not listed in official records.  General Layout: These sites consist of several general elements: Command Building: Two stories 40 feet in diameter. Access was by stairs and through two blast proof doors. Approximately 2,363 square feet of floor space not including stairway or vestibule. Due to the insulation of the earth, heating and cooling needs were minimal. Missile Silo: The missile silo was a huge structure 50 feet in diameter and approximately 185 feet deep. Access was from a 40 foot tunnel leading from the command building stairway. Missile silo had an approximate volume of 363,062 cubic feet.  Land: Land typically was 19-21 acres. Originally, the inner 5 acres of these sites were surrounded by a barbed wire topped chain link fence.  Status: All sites are now in private ownership, all materials were salavaged before they were sold but the structures remain intact as last reported in 1996.

Fort au Fer was constructed by British forces in 1775 on the coast of Lake Champlain, in Northern New York. Bizarrely, the fort remained under British control until 1796. In 1794, the United States and Great Britain came to an agreement (the Jay Treaty of 1794) to settle a wide variety of ongoing issues, including the British occupation of forts in Northern New York. After falling under American control, the fort eventually fell victim to a fire in 1805 and was destroyed. Notes: - The fort was located one mile south of Rouses Point - A large stone house from 1770 was fortified with cannon and entrenchments in 1775, with additional brick barracks and stockade.

Fort Lévis, eventually known as Fort William Augustus, was constructed by the French in 1759, and seized by the British in 1760 during the Seven Years’ War. The fort was originally named after French Marshal, François Gaston de Lévis, and rebranded by the British in honor of then head of the British Army and Duke of Cumberland, Prince William Augustus. The French constructed the fort near Ogdensburg, New York on an island surrounded by the St. Lawrence River. It was built for the purpose of supporting the existing Fort de La Présentation as a means to bolster a potential defense against possible British attacks on the area. However, this plan failed, and shortly after the fort’s seizure by the British, it was briefly maintained until its abandonment in 1766.
