The Bronze Age
Kökar was first inhabited over 3 000 years ago by seal hunters during the early Bronze Age. There is a site of stone chippings at Kalen which indicate early activity on the island.
There are remains of seal hunter residence where building sites, animal bones and fragments of pottery have been found back in the early 20th century. The fragments found in Otterböte indicate that the seal hunters actually were of the Lausitz tribe from the southern parts of the Baltic Sea, in today's Poland.
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.
The local museum was opened in 1988 and its purpose is to show how the people of Kökar lived in the 19th century and onwards to the 1940s. The now museum building, built in 1913, used to be an old school.
