Edward Harkness, the original owner, was a major benefactor of Yale University and the Metropolitan Museum of Art.
The estate’s gardens, originally designed by Beatrix Farrand, were restored based on the original 1906 planting plans.
The mansion was initially known as Eolia because the owner loved the Aegean Sea, which is associated with Aeolus, the ruler of the winds.
The estate features a rare sunken garden that remains one of the primary historical horticultural features in the park.
Mary Harkness willed the estate to the State of Connecticut specifically to be used for the benefit of the people.
The mansion served as a residence for the severely disabled for several decades after the state acquired it before being transitioned into a historic site.
Eolia is a 42-room Renaissance Revival mansion located within the 230-acre Harkness Memorial State Park on the Long Island Sound. Constructed in 1906 for Edward and Mary Harkness, the estate was designed by architect James Gamble Rogers. The architecture reflects an Italian villa style, characterized by its stucco facade and tiled roof. The grounds were landscaped by Beatrix Farrand, one of the founding members of the American Society of Landscape Architects. The mansion is situated on a bluff overlooking the coastline, offering panoramic views of the water. It serves as a prominent example of the Gilded Age summer estates once common in the region. The state of Connecticut acquired the property in 1952, preserving both the structure and the extensive gardens. Today, the park is managed by the Connecticut Department of Energy and Environmental Protection. The site remains a popular venue for outdoor weddings and public events.
