Block Island Southeast Lighthouse

The Southeast Lighthouse is the most recognizable landmark on Block Island. Built in 1875, it sits on the edge of Mohegan Bluffs with a 150-foot drop to the ocean behind it. The red brick tower is still an active aid to navigation, and on a clear day the light is visible 35 miles out to sea.

The lighthouse was moved 300 feet back from the eroding cliff edge in 1993 — one of the largest lighthouse relocations in US history. The museum inside tells that story and covers the island's maritime history. Tours run through the summer and are worth the short climb to the top of the tower.

The grounds are open year-round and free to walk. The museum and tower tours run seasonally, typically Memorial Day through Columbus Day.
