The first lighthouse on this islet was built in 1808 and another one was erected in 1866. The latter lighthouse was destroyed by Finnish forces at the onset of the Winter War of 1939-40 and the personnel were evacuated.[15] After the 1944 peace treaty between Finland and the Soviet Union, the island of Sommers was given to the Soviets, who also constructed a new truss lighthouse.
