The Cathedral of the Diocese of Skara is the centrepiece of the town and one of the oldest church sites in Sweden. The lower walls and parts of the choir date from the 12th and 13th centuries; the rest is a patchwork of medieval Gothic, Baroque interventions, and a thorough 19th-century rebuild that gave the cathedral its present soaring twin towers.
Inside, the highlights are the medieval crypt, a striking set of 20th-century stained-glass windows by Bo Beskow, and the elaborately carved choir. The cathedral is free to enter and usually quiet — Skara sees few enough tourists that you may have the nave to yourself.
