Harkness Memorial State Park


Enjoy the panoramic views of Long Island Sound from Eolia, the elegant summer mansion of the Harkness family set on over 230 seaside acres of sweeping lawns, with stately trees and spectacular gardens. Named Eolia, for the island home of the Greek god of winds, the mansion was built in 1906 and purchased by Edward and Mary Harkness in 1907. The 200+ acres were a working farm and the mansion served as the Harkness’ summer home.

The Roman Renaissance Classical Revival-style mansion has 42 rooms and includes a pergola (tearoom) and carriage house (support complex). Lush gardens flank the mansion on both the east and west lawns, and an Alpine Rock Garden adds to the beauty and splendor of the seaside panorama.

Eolia is available for weddings, private parties, seminars, conferences, luncheons and teas from March 1 to December 23.
