Katanpää Fortress Island

Katanpää served as a fortress island during the First World War. Today, Katanpää is a culturally historically valuable attraction. The island has barracks and a wooden water tower, two artillery batteries and the cobbled cannon roads leading to them.
The island's nature is versatile: shore cliffs, deep ravines, ancient rocky beaches and ancient forests. 
In summer, visitors can reach the island by ferry from both Uusikaupunki and Kustavi. Read more about Katanpää Island.
