Harkness Memorial State Park
A Gilded Age Estate on the Connecticut Shore
Harkness Memorial State Park in Waterford, Connecticut, is unlike any state park you’ve ever visited. Instead of wilderness, you’ll find a magnificently preserved 230-acre Gilded Age estate featuring a 42-room Renaissance Revival mansion, world-renowned gardens designed by Beatrix Farrand, and sweeping waterfront views of Long Island Sound. It’s a place where history, horticulture, and coastal beauty converge.
The estate was the summer retreat of Edward and Mary Harkness, beneficiaries of the Standard Oil fortune. Mary Harkness bequeathed the property to the State of Connecticut in 1950, ensuring this extraordinary landscape would remain accessible to the public forever.
Eolia — The Mansion
The centerpiece of the park is Eolia (named for the Greek island of the god of winds), a stunning 42-room mansion built in 1906–1907. The Renaissance Revival masterpiece features 20 bedrooms, 14 baths, and 11 fireplaces, along with an elegant pergola and carriage house. Guided tours are offered on weekends and holidays from Memorial Day through Labor Day. The mansion is also available for weddings, private events, and conferences.
The Gardens
The park’s six themed gardens are its greatest treasure, largely created by Beatrix Farrand — one of America’s most influential landscape designers and a founding member of the American Society of Landscape Architects.
- East Garden: A traditional English cutting garden overflowing with seasonal blooms
- West Garden: A formal Italian-inspired garden with geometric beds and sculptures
- Boxwood Parterre: Intricately shaped boxwood hedges in classical patterns
- Alpine Rock Garden: A miniature mountainscape with delicate alpine plantings
Extensive restoration in the 1990s returned the gardens to their 1930s splendor, complete with original loggias, water features, wrought iron fencing, and hundreds of historically accurate plantings combined with Mary Harkness’s collection of Asian statuary.
