It’s hard to miss the Franziskanerkirche – it’s the tall, yellow spire on the river opposite the Kunsthaus. You may wonder why an order devoted to poverty has such a ruddy big tower. Thanks to the Franziskanerkirche’s strategic position near the old city walls, the city authorities decided that it also needed to function as a defensive fortification. The tower was built in A.D. 1636-1643 and the onion dome was added in A.D. 1740.
It’s a safe bet to say that if you find an Austrian church with 20th century stained glass (like this one and the Stadtpfarrkirche), the windows were blown out by World War Two bombing.
