Museum of St Helena, Local history museum in Jamestown, Saint Helena

The Museum of St Helena is a museum in lower Jamestown, Saint Helena, housed in a late-18th-century stone building that formerly served as the old power station, at the foot of Jacob's Ladder. Its two floors hold collections covering the island's maritime, military and social history, much of it salvaged from shipwrecks around the island, with a small gift and book shop and an adjoining gallery for temporary exhibits.

The museum opened in 2002 inside a former power station from the late 1700s, which had originally supplied electricity to Jamestown. Its opening marked 500 years since European sailors first arrived on the island.

The museum is run by the Saint Helena Heritage Society, founded in November 1979, which opened it in 1980. Many exhibits were salvaged from shipwrecks around the island, and the collection covers the maritime, military and social history of this British Overseas Territory. A small gift and book shop and an adjoining gallery for temporary exhibits are part of the museum.

The museum occupies a late-18th-century stone building at the foot of Jacob's Ladder in lower Jamestown. The two floors are reached by stairs, and the adjoining gallery hosts temporary exhibits. Plans exist to expand into the adjacent PWD Stores building.

The building that houses the museum once generated electricity for Jamestown, a role that is not obvious from its stone exterior. This former function shows how the island found practical solutions in a remote setting long before modern supply lines existed.
