Heggholmen lighthouse, established in 1826, functions as a harbor lighthouse and has an important historical significance for navigation in the Oslofjord. Built in 1876, the current lighthouse building is an example of 19th century architecture and has been part of the coastal landscape for over a century. The lighthouse was automated in 1959, which has contributed to a more efficient operation.
In 1997, Heggholmen lighthouse was protected under the Cultural Heritage Act, which ensures the preservation of the building's cultural and historical values. The lighthouse is owned by the Port of Oslo, but is not available for visits or accommodation. Heggholmen lighthouse is therefore primarily an attraction for those interested in maritime history and cultural heritage, but it is important to note that it is not possible to visit the site.
