Having had its top knocked off during the Turkish siege of 1529, the Minoritenkirche’s stunted octagonal tower is a landmark of the Innere Stadt. Completed in the early 14th century it was transformed to Baroque architecture, finally returning to simple Gothic styling in 1784 on the orders of Ferdinand von Hohenberg. Inside, a superb mosaic copy of Leonardo da Vinci’s ‘Last Supper’, originally commissioned by Napoleon, adorns the north wall. This French cathedral style church, named after the Minoriten Franciscan monks, is the subject of Adolf Hitler’s most renowned watercolour painting.
