Treetops (state park)

Treetops is the former estate of torch singer and actress Libby Holman. In 2001, a successful effort was made by local citizens to save the estate from development. As a result, 94 acres of pristine grounds were preserved as a state park, with a further 11 acres around the Treetops mansion covered by a conservation easement. Many rooms in Holman's mansion, including the studio of her third husband, abstract artist Louis Schanker, have been restored by its current owners.
The property forms the southernmost portion of Mianus River Park and is overseen by the Connecticut Department of Energy and Environmental Protection as Mianus River State Park.
