Castle Island
Stefan Bielinski

Variously called Castle Island, Nassau Island, Marte Gerritse's Island, Patroon's Island, and Westerlo Island, the large land form on the west side of the Hudson River was separated from the mainland by the passage of the Normanskil (sometimes called the "Normanskill Creek") behind it as it wound its way into the Hudson.

trading post on Castle IslandThe island has a rich history and many historical traditions! Inhabited by both Mohawk and Mohicans, it even was said to be the site of a French trading post built during the sixteenth century. The first documented inhabitation probably occurred in 1614 when a trading outpost known as Fort Nassau was erected by the Dutch West India Company. Located on the Hudson River flood plain, the rudimentary "fort" was washed away by flooding in 1617 and/or 1618 .

Fort Nassau was replaced by the building of Fort Orange in 1624. By the 1640s, the fertile island was divided into farms and leased to tenants. The first farm on Castle Island is said to have been called "Rensselaersburgh" and was established in 1630.

Early tenants included Brant Peelen, Adrian Vanderdonck, Cornelis Segerse, and Marte Gerritse Van Bergen.Castle Island - 1645

Marte Gerritse held a lease on the island from before 1664 until the 1690s. In 1689, "21 farmers belonging to Capt. Marten Gerritse* Compe" subscribed for defense. During that time, Castle Island had been among the most productive farms in Rensselaerswyck. Gerritse tried to purchase the island but was rebuffed by the Van Rensselaers and finally was displaced and replaced as tenant by members of the Staats family.

The Albany city charter of 1686 fixed Albany's southeastern boundary as the "tip of Marte Gerritse's island."

Throughout the balance of the colonial period, the island was included in the manor of Rensselaerswyck and was leased to a succession of advantaged area residents. In 1744, John Milne, former rector of St. Peters Anglican church, was its resident farmer. Patroon's Island - 1767 Then, British retainer Hitchen Holland held the lease until his death in 1762. In 1767, it was called "Patroon's Island" and was leased to British officer John Bradstreet. On patroon Stephen Van Rensselaer's death in 1769, the island passed to his widow, Catherine Livingston Van Rensselaer. It also was known as "Westerlo Island" most likely because the patroon's widow married Dominie Eilardus Westerlo in 1775.


By the 1880s, the island had about 160 acres of "fertile land . . producing fine crops in favorable seasons." It also had two ironworks on its northern end. At that time, it belonged to the town of Bethlehem.

From 1909 to 1927/8, the island was used as an airfield called "Quenton Roosevelt Field." Famed aviators Glenn Curtis and Charles A. Lindbergh landed on the airstrip - the predecessor of the Albany Airport.

New York State created the Albany Port District in 1931 which encompassed 200 acres (including the island) within the city of Albany and another 35 acres across the river in Rensselaer. Dredging and construction followed. In 1932, the island had been transformed and officially opened as the Port of Albany.

Cornelis Segerse took up the farm formerly occupied by Brant Peelen, deceased, which was one of the two farms on Castle Island, near Albany. In 1646, he took over from Adrian Vanderdonck the other farm for the remaining 3 years of its lease, and thus came into possession of the entire island. In 1651, an inventory of the farm of Cornelis Segers showed that he was the owner of 13 horses and 22 cows, and that the farm contained 70 morgens, and the rent was 1210 guilders. This farm was called Welysburgh.

In 1744, the island was visited and described by the Marylander Dr. Alexander Hamilton.
