Gillette Castle State Park is off SR 82 at 67 River Rd. Overlooking the Connecticut River, the park was the estate of William Gillette, noted actor and playwright renowned for his portrayal of Sherlock Holmes. The focal point of the 184-acre park is the 24-room, 8,500-square-foot mansion, which sits upon a rock formation known as the “Seventh Sister.”
Designed to look like a medieval ruin, the fieldstone castle was built 1914-19. Intricate woodwork in the interior includes 47 hand-carved doors, each with a different carved latch. Woodland trails on the grounds cross the stone bridges and trestles of Gillette's narrow-gauge railroad.
