Castle Island (New York)

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.
