Mohni Lighthouse (Estonian: Mohni tuletorn) is a lighthouse located on the island of Mohni (in the Gulf of Finland), in Estonia.[3]


The original wooden lighthouse was built in 1806, and replaced with the 20 metre concrete structure in 1852.[4] Due to the harsh Nordic climate, the outer bricks of the lighthouse have heavily deteriorated and a new layer of bricks (including an additional 7 metres in height) were added in 1871. The lantern room of the lighthouse was built by a Latvian based factory in Liepāja, and the dioptric apparatus was made by Chance Brothers & Co in Great Britain.

Due to the continuous deterioration of the lighthouse's outer brick surface, the lighthouse was reinforced with a layer of concrete after World War II; this layer was removed in 1998. Next to the lighthouse is the lighthouse keeper's house.[5]
