Dark Island, River island in Saint Lawrence Seaway, United States.
Dark Island stands in the Saint Lawrence River near Chippewa Bay, featuring dense vegetation and natural rock formations along its shoreline.
Frederick Gilbert Bourne, president of Singer Manufacturing Company, commissioned the construction of Singer Castle on Dark Island between 1902 and 1905.
Singer Castle incorporates numerous secret passages, a 28-room layout, and architectural elements inspired by structures from Woodstock, England.
The island remains accessible through guided boat tours departing from nearby harbors, with specialized castle tours available from May through October.
The castle contains an observation tower rising four stories above the main structure, allowing visitors to view both American and Canadian waters.
