Main image

Keri Lighthouse is a navigational lighthouse located on Keri Island in the Gulf of Finland, within Harju County, Estonia. It is a longstanding maritime aid marking shipping approaches in the eastern Gulf of Finland.

The site is compact - the lighthouse and a few island structures occupy a small rocky islet surrounded by open sea. Visitors typically see the tower, coastal rock, and seabirds; there are no visitor services on the islet.

The light station has served maritime traffic for many decades and the island has been used historically to support navigation in the gulf. The structures on the islet have changed with repairs and maintenance over time but the location’s role as a maritime marker has remained.

Geographically the lighthouse sits offshore in the Gulf of Finland, administered from Harju County. The nearest larger landfall is the Estonian mainland; access requires a boat trip from the Estonian coast.

  • Access: The lighthouse sits on a small rocky islet off the Estonian coast and is reachable only by private boat or organised excursions during calm weather.
