The church of Jomala is dedicated to the patron saint of Åland, St. Olav. It is the oldest surviving church in Finland and it is situated in the village of Prästgården. The oldest parts of the church date from the 13th century. The church tower is 52 meters tall and there is also a memorial for all the Ålanders who emigrated. Another memorial refers to sailors who lost their lives on sea. The "King of Åland" Julius Sundblom is buried here. A large medieval cemetery with graves from the Iron Age can be visited behind the church.
