About Hovedøya#
Hovedøya is a small island in the Oslofjord within Oslo municipality, known for its archaeological remains and recreational shoreline.
The island’s most notable feature is the visible ruins of a Cistercian monastery dating from the 12th century, together with open grassy areas, wooded paths and small beaches that attract walkers and swimmers. Visitors use short trails to move between the ruins and shoreline.
The island also preserves traces of later military use and shoreline defence, and its natural vegetation provides a green escape close to the city. Facilities are minimal, emphasising short visits and outdoor recreation.
