New London Harbor Lighthouse

Highlight • Monument

New London Harbor Lighthouse is a historic landmark built in 1801 for the fishing and whaling industries. It is Connecticut's oldest and tallest beacon, and the fourth oldest in the US. The keeper's house is closed to the public; however, tours are available if you have over six people. The unique advantage is that during a tower tour on a clear day, you can see up to 7 lighthouses - two in Connecticut and five along New York in the sound. More lighthouses can be seen from this spot than any other place on earth.

Harkness Memorial State Park

Highlight • Historical Site

Harkness Memorial State Park, located in Waterford, Connecticut, encompasses 304 acres, featuring the Renaissance Revival mansion "Eolia" surrounded by formal gardens and greenhouses. Once the summer home of philanthropists Edward and Mary Harkness, the estate was designed by Lord & Hewlett in 1906–1907. Landscape designer Beatrix Jones Farrand enhanced the grounds from 1918 to 1929. Mary Harkness bequeathed the estate to the state in 1950, and it became a state park in 1952. Listed on the National Register of Historic Places, Eolia comprises a 220-acre historic district with contributing buildings and structures. The park is managed by the Connecticut Department of Energy and Environmental Protection.
