The most famous landmark in the town of Ösmo is a church that's almost as old as Christianity in Sweden—parts of it date from the 12th century, while the earliest missionaries arrived here in the 11th century. The building's formidable square stone tower likely provided shelter for residents during attacks from the Danes and others, but the church is best known for a series of frescoes. In the 15th century, after its wooden arches were replaced with brick ones, more than 60 panels were painted with scenes largely from the Bible. One notable exception was a series known as "The Witch and Her Hare." While other panels were touched up in the 18th and 19th centuries, these were left in their original state, as they were considered inappropriate for a church. Visitors today can see them much as they would have appeared some five centuries ago.
