Ruggles Mine

Ruggles Mine is an open-pit mine that was turned into a tourist attraction. It was closed but was sold multiple times and reopened in 2024. The mine is located 40 miles (64 km) northwest of Concord, New Hampshire, in the town of Grafton, a short distance from Route 4 at the village green. The spacious pit includes tunnels and underground chambers, some of which are filled with water. Visitors are allowed to keep any of the various minerals that they find on the mine floor or that can be hammered loose from the walls of the pit.
