Harkness Memorial State Park is a public park located on Long Island Sound in the town of Waterford, Connecticut. Eolia, a 42-room Renaissance Revival mansion with elaborate gardens and greenhouses, is the center of the 304-acre park. The mansion was built in 1906 by William and Jesse Stillman.
The Harkness Family left the property to the State of Connecticut in 1950 and it slowly fell into disrepair and closed to the public.
Kronenberger & Sons performed a complete exterior envelope and interior restoration to the entire building. This included restoring masonry, wood, metal, plaster, molding details, paneling, trim, doors, windows, tiles, and more. The mansion reopened to the public in 1998.
Harkness Mansion is #86003331 on the National Register of Historic Places.
