The national sanctuary of Norway, built over the grave of St. Olav. Work began in 1070, but the oldest parts still in existence date from the middle of the twelfth century. These are in the Romanesque style, while most of the cathedral is Gothic in style. The building was completed in about 1300, but after being damaged several times by fire, it lay largely in ruins at the time of the Reformation in 1537. In 1869 extensive restorations were begun, and a century later it was again restored to its original grandeur. The stained glass dates from the early 20th century. The sculptures on the west front are by leading Norwegian artists, and the most recent was erected in 1983
