USS Nautilus (SSN-571)

Highlight • Monument

Nautilus is the first American nuclear-powered submarine. Still without ballistic missiles, only equipped with "normal" torpedoes, but compared to the technology of the Second World War, it is a huge step forward. Life on board is not easy for the crew either, but at least bearable. Take a look, because there are not so many opportunities to view a nuclear submarine anywhere in the world...

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.

November 15, 2025, Haley Farm State Park Entrance

Haley Farm State Park is a state park in the U.S. state of Connecticut, located within the municipality of Groton. The park's purpose is to preserve farmland that has been cultivated since colonial times (1776-1876). The site was once home to Caleb Haley's dairy farm. In 1953, the land was sold to A. C. White, who built Mumford Cove and subsequently sold 198 acres (80 hectares) to the State of Connecticut. In 1970, the land was reclaimed by the state for $300,000. In 1975, a bicycle trail was established from Mystic to Noank, partially traversing Haley Farm State Park. An additional 57 acres (23 hectares) were purchased for $913,300 and added to the park in 2002. The park now encompasses 267 acres (108 hectares) and is directly adjacent to the Bluff Point Coastal Reserve. The park is reserved for cyclists and hikers. ... https://de.wikipedia.org/wiki/Haley_Farm_State_Park

Nautilus was the first American nuclear-powered submarine. Still without ballistic missiles, "only" equipped with classic torpedoes. But compared to the old Fiesel submarines from the Second World War, it is a huge step forward. The crew accommodation alone has improved by a lot. But visit this boat yourself! Admission is free!
