Harkness Memorial State Park (230 acres (93 ha)) is a Connecticut state park and botanical garden located in Waterford, Connecticut, on the Long Island Sound. The park comprises a 42-room Renaissance Revival mansion, designed by the New York architectural firm of Lord & Hewlett, with a surrounding area containing Italian, Oriental, and Cutting gardens and greenhouses.
The park was formerly Eolia, the estate of Edward Harkness, heir to a fortune initiated by his father Stephen V. Harkness's substantial investments in John D. Rockefeller's Standard Oil, who purchased the mansion in 1907. From 1918 to 1929, extensive improvements were made by landscape designer Beatrix Jones Farrand. Eolia was left to Connecticut in 1950 and became part of the State Park system in 1952.
As Eolia—Harkness Estate, it was listed on the National Register of Historic Places in 1986. The 220-acre (89 ha) district that was listed included 15 contributing buildings and two other contributing structures.
