The Front Museum, on the old border line at Lappohja about 25 kilometres north of Hanko town, covers the strange interlude of the Hanko Soviet Naval Base (1940-41) and the Finnish recapture of the peninsula. The exhibits — set in restored wartime bunkers and trenches — combine military hardware, daily-life material, and a strong if cramped exhibition on the lives of Finnish civilians displaced from the leased territory.
Open daily June through August, weekends only in May and September, closed in winter. Allow ninety minutes. The setting alone — Finnish pine forest with the original concrete fortifications still in place — makes it worth the drive. Drivers can continue north to the main Helsinki road; cyclists can use the rail trail back into Hanko town.
