The church of St. Anne was built in the site of the old monastery church during the reign of king Gustav III and is located on the island of Hamnö. It is next to the ruins of the monastery. The clocktower was built in the 19th century. The clocktower had to be restored after an Autumn storm damaged it in 1978. A model of a sailing ship hangs in the church. It was given by a local sailor who had been captured by Turkish pirates but who later managed to escape. The model has 64 cannons.
