Ulkokalla Lighthouse

Ulkokalla Lighthouse is a coastal lighthouse on Ulkokalla island in Kalajoki, Finland, featuring a brick tower with a height of about 14 meters and a classic lantern room at the top. The structure stands on a small islet in the Bothnian Bay and serves to guide ships navigating in the region.

Architect Hampus Dalstrom designed this structure in 1871, and it began operating in 1872 with a Fresnel lens system imported from France. The lighthouse has remained a stable navigation aid in the northern waters since then.

The lighthouse serves as a vital navigation marker in the Gulf of Bothnia, helping ships safely navigate the northern Finnish waters. Visitors can directly experience the importance of this landmark for maritime safety in the region.

The lighthouse is located about 20 kilometers from the mainland on a small island in the Bothnian Bay, roughly 400 meters long and 200 meters wide. Access is only possible by boat, and visitors should check weather conditions and access regulations beforehand.

Since 1986, this lighthouse has been powered by wind and solar energy, emitting three white flashes every 20 seconds. This combination of historic design with modern energy sources makes it a distinctive navigation aid in the region.
