Narrows Fort: 1776, Brooklyn. A patriot redoubt near Denyse Point on the Narrows, future site of Fort Hamilton. Americans withdrew at British landing of August 1776. Used by the British until their withdrawal from NYC in 1782.

Fort Nassau: Albany. First Dutch trading post and stockade 1614-1618. Built on Castle island East side of Hudson River South of present Rensselaer (Patroon's Island). Said to have been the first permanent building in New York. Washed out by a river flood. Fort Orange built on the riverbank in 1624. Island has merged with shore since then. The following was submitted by Cliff Lamere: The island was on the west side of the river. It was south of Albany, not Rensselaer. The "Patroon's Island" comment should be omitted. It is an island north of Rensselaer and has nothing to do with Fort Nassau. Mr. Lamere also submitted the following taken from: History of the State of New York: First Period, 1609-1664 by John Romeyn Brodhead (1853), pg 55. "Hendrick Christiaensen... constructed a trading house on "Castle Island," at the west side of the river, a little below the present city of Albany. This building, which was meant to combine the double purposes of a warehouse and a military defense for the resident Dutch traders, was thirty-six feet long, by twenty-six feet wide, inclosed by a stockade fifty-eight feet square, and the whole surrounded by a moat eighteen feet in width... The little post was immediately named "Fort Nassau." It was armed with two large guns, and eleven swivels or patereros, and garrisoned by ten or twelve men." "Said to have been the first permanent building in New York." I haven't heard that, but it might be true. New Amsterdam (NY city) also had people there in 1614. I wonder what the writer meant by permanent. Built about 1614, it was destroyed the following Spring by floods that were carrying blocks of ice. It lasted less than a year. That wasn't what I'd call permanent. The fort was rebuilt nearby onshore, but on the floodplain. In 1618 it was abandoned by the Dutch.

The New Scotland Avenue (Troop B) Armory was built in 1914. It was designed by Lewis Pilcher. The armory is sited on a relatively flat, approximately 9 acre lot, the northern half of which is occupied by four large, modern, concrete block storage and maintenence buildings. Only the northern half of the property of approximately 4.5. acres, was included in the Historic Register nomination. The first unit to use the armory was Troop B, later a Machine Gun Company in WWI. Taken over by the 106th AAA AW Battalion (10th Regt) (1950-52), renamed 127th AAA AW Battalion (1952-53), renamed 127th AAA Battalion (1953-59), renamed 210th Artillery 1st AW Battalion (1959-60), converted and renamed 1st Bn 210th Armor in 1960 until deactivated in 1993), occupied by B Co 1 Bn 101 Cav and various detachments until closure and sale in 1999. The roughly T-shaped armory consists of a two-story administration building and a three and one-half story drill shed. Both sections rest on raised, parged concrete foundations with granite water tables. The walls are constructed of structural steel framing sheathed with brick curtain walls. The main block and bastions are encircled by crenelated brick parapets with rifle slits, stone coping, a stone beltcourse, and a machicolated brick cornice. The bastions are ornamented with high relief stone rendering of the seal of New York State. The five-bay-deep side elevations of the administration building each feature a slightly projecting, three-bay-wide center pavillion with double doors surmounted by large, multi-paned transom lights and a segmentally arched brick surround with a stone keystone. The two most notable and intact spaces are the company meeting room on the first story of the administration building and the large, unobstructed drill shed. The company meeting room features a simple brick mantel and paneled wainscotting. The New Scotland Avenue (Troop B) Armory was added to the Historical Register in June, 1991.

New Windsor Cantonment: 1782-83, Vails Gate, Orange County. During much of the Revolutionary War, New Windsor served as the major depot for the Continental Army and Army Medical Dept. In October 1782, the troops began to arrive and set up tents, while they began building their huts. This encampment or cantonment covered 1600 acres and quartered 6000-8000. Here this army built a log city of over 700 huts for the soldiers and many other out buildings, guardhouses, blacksmith shops, stable, kitchens, hospital, and a 110 by 30 foot assembly hall called the "temple" for worship service were constructed. Troops furloughed June 1783, buildings sold off September 1783. In order to reward the fidelity and faithfulness of three soldiers, Gen.Washington ordered the establishment of an honor, the Badge of Merit be bestowed on them. Today, this honor is known as the Purple Heart. The Town of New Windsor acquired a 167 plus acre tract consisting of much of the former hut sites, and since 1936, the Town of New Windsor and the National Temple Hill Association have strived to ensure the preservation of this the final winter encampment. In addition, the temple site is operated by the State of New York, known as the New Windsor Cantonment with a museum established on site in 1965. Located there is the Mountainville Hut, believed to be a survivor from the encampment. Nearby is Knox's Headquarters - a 1754 stone house built by noted stone mason William Bull, for John Ellison off Forge Hill Road.

Niagara Falls Air National Guard Base: Niagara Falls. In 1969 the BOMARC site was totally removed for construction of the Air Base.

Niagara Falls BOMARC Base: 1961, Niagara County, Niagara Falls. BOMARC Missile Site operational here 1961-1969. The BOMARC B was a Surface-to-Air Cruise Missile with a length of 43 feet, 9 inches and a wingspan of 18 feet, 2 inches. Its range was 440 miles. Essentially an improved and streamlined Bomarc A, (see Suffolk ) the Bomarc B, designated IM-99B, was flight tested in 1959. The Bomarc B added a Thiokol solid rocket booster housed under the missile's body. Capable of producing a thrust of 50,000 pounds, the booster fired for 30 seconds before it was jettisoned. Extra tankage was fashioned within the body of the Bomarc B to house additional JP-4 fuel for two improved Marquardt ramjet engines, each of which had a thrust of 14,000 pounds. This upgraded propulsion system nearly doubled the range of the Bomarc weapons system. The missile also incorporated a more advanced Westinghouse radar system. Boeing delivered a total of 349 Bomarc B missiles to the U.S. Air Force between 1961 and 1965. These either replaced aging Bomarc A missiles at existing bases or facilitated Bomarc B deployment at new sites. Two 28 Missile Squadrons of new Bomarc B deployments occurred Niagara Falls Municipal Airport, New York. Bomarc was the first weapons system to employ an active homing system. Interceptions were controlled by a Semi-Automatic Ground Environment (SAGE) system from Hancock Field AFB, see SAGE, designed to alert and control the SAM toward its target. The site deactivated in 1969.

Fort Niagara (Old): 1726, Niagara County, Youngstown. After three previous short term forts (Fort LsSalle) 1669, in ( Fort Conti) 1679 and (Fort Denonville) 1687, the French established a permanent presence in 1726. Starting in June a palisaded two story stone "chateau" with attic was built. Cannon were secretly installed on the second floor (garret) and the attic. In October 1755 the fort was improved with new entrenchments, a barracks for 400, rebuilt palisades of oak, a moat, and improved fields of fire to 1/4 mile. Attacked by Bg. Prideaux (killed) and Sir William Johnson and captured 27 July 1759. Rebuilt through September 1759 under Sir William. Massive stone north and south redoubts built in 1766-77. The British surrendered the fort to the new U.S. government in 1796. The British retook the fort during the war of 1812 and returned it after the war. Brick walls and a moat were added in 1861. For more information see: www.oldfortniagara.org/ See: Fort Niagara under the French, English, and the United States by Henry R. Marshall. ​​​​​​​Fort Niagara (New): 1841, Niagara County, Youngstown. In 1841 new building construction was started adjacent to the old fort's battlements consisting of Barracks, Officer's Quarters, and Life Saving Station. More buildings were added on the surrounding plain during its use as a training post from 1903. In 1917 through 1922 it was an Officer's Training Camp and ROTC. From 1922 to 1940 it was the Base for the 28th Infantry Regiment, during which period many improvements and preservation work was done. From 1940 to 1943 it was a Reception Center for Army draftees, and more than 11 new buildings were constructed. From 1943 to 1945 it was a Reception Center, then Separation Camp, and also served as a prisoner of war camp. In 1945 the base was closed and by 1946 was being used for Veteran's housing. Most of the Base, except for housing was turned over to the Niagara Frontier Parks Commission. Fort Niagara (NIKE): 1950, Niagara County, Youngstown. In 1950 a detachment of the US Air Force occupied some building, and by 1953 families were notified to vacate. The Fort was occupied by the 2nd Antiaircraft Group and rehabilitation and modernization was completed by 1955. Nike sites controlled from here were at Model City, Cambria Center, Grand Island, Millersport, Lancaster, Orchard Park, and Hamburg. Nike-Ajax Missile operations until 1963 when deactivated. Most of the buildings were subsequently removed and development started as historical site in 1963 to present, and now owned by the State Parks and operated by a not-for-profit organization.
