Gillette Castle is a fieldstone fortress built between 1914 and 1919 by actor William Gillette, best known for his stage portrayal of Sherlock Holmes. Situated atop the southernmost of the 'Seven Sisters' hills in East Haddam, the structure overlooks the Connecticut River. The castle features 24 rooms and was designed by Gillette to mimic a medieval stronghold. It includes distinctive architectural elements such as hand-hewn white oak woodwork, secret doors, and hidden mirrors. The property is currently managed as a Connecticut State Park and historic landmark. The interior retains many of Gillette's original furnishings and personal curiosities. Visitors can explore the grounds, which include walking trails and scenic overlooks of the river valley. The stone construction utilizes locally quarried materials.
The terrace area on the south side of the castle provides the best panoramic view of the Connecticut River.
