Dark Island, River island in Saint Lawrence Seaway, United States.
Dark Island is a river island in the Saint Lawrence River near Chippewa Bay, marked by dense vegetation and natural rock formations along its shoreline. The island is home to a large castle with many rooms, underground passages, and a tall observation tower.
An industrialist commissioned the construction of a grand castle on the island in the early 1900s as a display of wealth and status. The building project took several years and used advanced construction techniques of that era.
The castle on the island blends medieval and modern design, reflecting how wealthy residents of that era imagined European luxury. Its rooms and decorations show the tastes and ambitions of early 1900s American industrialists who built grand homes as symbols of their success.
The castle is accessible only through guided boat tours departing from nearby harbors, with specialized castle visits offered during the warmer months. Visitors should plan for water travel and wear sturdy shoes, as the island requires boat access from the river.
The castle contains hidden passages and secret rooms that make it feel like a maze, where visitors can easily get lost while exploring. These underground corridors and concealed spaces add a layer of discovery to the visit.
