Founded in 1083, the abbey you see today is mostly baroque due to restoration after a devastating fire in the early 18th century. Aside from the grand view back across the Danube Valley from its garden terrace and restaurant, the abbey’s highlights include the Imperial Staircase with a heavenly ceiling fresco painted by Paul Troger in 1739, and the over-the-top baroque interior of the Stiftskirche (which has a Kremser Schmidt work in the crypt). Fully guided tours take in the abbey’s Imperial Wing, church and summer vestry; shorter tours explore either the Imperial Wing or the church and vestry.
