Lembit

The Estonian submarine Lembit is a museum vessel at the Seaplane Harbour in Tallinn, Estonia. It measures around 60 meters (200 feet) and includes four torpedo tubes, one anti-aircraft gun, and storage for twenty sea mines.

The Vickers-Armstrongs shipyard in Britain built the vessel in 1936 for the Estonian Navy. After Soviet occupation in 1940 it was incorporated into the Baltic Red Banner Fleet and remained afloat until 2011.

The name comes from Lembitu, a 13th-century Estonian leader who resisted crusaders. Today the vessel stands as a symbol of the country's brief interwar independence and attracts visitors interested in naval defense.

Visitors can walk through the inner compartments, including the control room, torpedo station, and crew quarters. The passageways are narrow and low, so comfortable footwear is recommended.

It is the only preserved pre-war military ship in the Baltic region and spent 75 continuous years in the water. After drydocking in 2011 it was moved into a museum hall and remains fully accessible for walkthrough tours.
