If you're tired of baroque ornamentation, visit this church of the Friar Minor Conventual, a Franciscan order also called the Minorite friars (inferior brothers). Construction began in 1250 but was not completed until the early 14th century. The Turks damaged the tower in their two sieges of Vienna, and the church later fell prey to baroque architects and designers. But in 1784, Ferdinand von Hohenberg ordered the baroque additions removed; and the simple lines of the original Gothic church returned, complete with cloisters. Inside you'll see a mosaic copy of da Vinci's The Last Supper. Masses are held on Sunday at 8:30 (in German) and 11am (in Italian).
