The Friends of Gillette Castle State Park is an all-volunteer, non-profit group dedicated to the preservation, restoration, and conservation of Gillette Castle and its park-like grounds, located within the Seven Sister Hills along the Connecticut River. We work closely with the Connecticut Department of Energy and Environmental Protection (DEEP) to promote and care for this spectacular and popular state park.

Founded in 1998, the Friends of Gillette host events throughout the year, both to raise funds for the park and to educate the public about the site’s noteworthy history. We invite you to join and support us whether you live nearby or far away. We welcome new members! We make a difference because of you!

We are very grateful for all donations.
