The church of St Olaf in Olsker is one of the four rotundas, which are located on the Danish island of Bornholm. It's a simple almost austere building founded in the 12th century, which shows the typical features of the Romanesque building. The church’s walls are very thick and heavy, whereas the windows are small and positioned high so that the temple could also serve a defensive function in the event of danger. St. Olaf II is the patron of the church – in the 11th century he was the king of Norway and took the trouble to introduce Christianity in his country. Along with other buildings of this type the church of St Olaf fits perfectly into the idyllic landscape of the northern island and is often visited by tourists.
