David I established a bishopric in this Celtic town in the mid-12C. Although the church was built in the 13C (west entrance), it has since been drastically modified. The square tower dates from the 13C-15C. Inside, there are two sculpted stones, both excellent examples of Pictish art. The curved tombstone probably dates back to the 11C. The stained-glass windows are the work of 20C masters, such as Douglas Strachan, Gordon Webster and William Wilson.
