Yttergrund Lighthouse

Yttergrund Lighthouse is a steel structure standing 43.6 meters tall on an island near Kristinestad on Finland's Bothnian coast. Its red and white painted exterior rises prominently above the surrounding waters and marks a key navigational point for passing vessels.

Construction of this lighthouse began in 1892, when it held the distinction of being Finland's tallest navigational structure at the time. The beacon initially burned kerosene before being converted to acetylene fuel in 1931.

The keeper residences surrounding the tower reveal how lighthouse staff lived on this island, with family life woven into the daily routine of maintaining the beacon. Their gardens and small structures remain visible traces of this working maritime community.

Access to the lighthouse is gained through Kilhamn harbor, which offers a marked fairway leading to a maintained pier on the island. Tidal conditions and wind should be considered before planning a visit, as the exposed island location brings maritime weather throughout the year.

The steel construction of this tower differs from most Finnish lighthouses, which were typically built from brick or stone, making it a noteworthy example of maritime engineering at the time. Its design reflects an unconventional approach to lighthouse building in the Nordic region.
