Kallo Lighthouse is a functioning navigational aid located on the rocky Kallo headland in Pori, Finland. Built in 1884, the current concrete structure replaced an earlier wooden tower and stands as an iconic symbol of the Mäntyluoto harbor area. The lighthouse utilizes a reinforced concrete frame and features a distinct white-painted finish. It serves as a vital beacon for maritime traffic entering the Port of Pori. The surrounding terrain consists of rugged granite cliffs exposed to the harsh conditions of the Bothnian Sea. Visitors can explore the immediate shoreline, which offers unobstructed views of the open sea and coastal skerries. The site is situated at the edge of a specialized port facility, blending industrial maritime history with natural coastal scenery.
The shoreline rocks on the western side of the lighthouse, capturing the tower against the horizon and incoming waves.
