Dating the submarine preserved in Tallinn

Was the submarine near the ferry port a salvaged British First World War boat?

The museum boat is in Tallinn: an interwar submarine that served during the Second World War.

The museum boat is placed near Tallinn's ferry port. Its construction belongs to the interwar years, correcting the question's First World War dating. It subsequently served during the Second World War. The exhibition occupies a former seaplane hangar, but the vessel's name is not established in this exchange.
