Carleton Island, River island in Saint Lawrence River, New York.
Carleton Island is a river island in the Saint Lawrence River in New York with rocky shores, forested areas, and the remains of historical fortifications. The island also holds the Wyckoff Villa, a large mansion built in the late 1800s.
During the American Revolutionary War, the island served as a strategic British military outpost with Fort Haldimand functioning as a naval station and supply depot. After the conflict ended, private owners developed the island and eventually built the mansion that still stands today.
The Wyckoff Villa reflects how wealthy families chose to build summer homes along the Saint Lawrence River in the late 1800s. The residence shows the architectural preferences of that era and how people used island properties as private retreats.
The island is only accessible by private boat since no regular ferry service connects the mainland to this location. Visiting during warmer months makes the water crossing more pleasant and the island easier to explore.
William Wyckoff spent just one night in his mansion on the island before his own death, which occurred shortly after his wife had passed away. This tragic episode remains part of the place's story and adds a poignant layer to its history.
