Sea Museum

The former Soviet coastguard barracks at Käsmu (Captains' Village) now shelters the Sea Museum. In the 1920s a third of all registered boats in Estonia belonged to this village; at one time there were 62 long-distance captains living here. From 1945 to 1991 the entire national park's coastline was a military-controlled frontier, with a 2m-high barbed wire fence ensuring villagers couldn't access the beach or sea.

The museum has photographs and memorabilia tracing the history of the village and exhibits on marine life from the area. It also hosts the Viking Days festival in August, when Vikings of all nations congregate for a bloodless battle.
