Singer Castle

Dark Island, a prominent feature of the Saint Lawrence Seaway, is located in the lower Thousand Islands region, near Chippewa Bay. It is a part of the Town of Hammond, in St. Lawrence County, New York.

A historic landmark on the island, "The Towers", was long known as "Dark Island Castle" until recently renamed "Singer Castle". The island is situated only a few yards south of the Canada-United States border that runs along the river.

The castle features 28 rooms, including bedrooms, bathrooms, a large Drawing Room, library, and kitchen. Within the walls is a network of secret passageways that are accessible from various locations, one of which is a panel in the library that, at one time, could be opened by pulling a specific book from a nearby shelf, triggering the locking mechanism.
