Maria am Gestade, one of Vienna's few surviving Gothic structures, was constructed between the years of 1394 and 1414. Believed to be first built from wood by Danube boatsmen around 880, the church was reconstructed with stone to make it a lasting piece of architecture. The nave was built narrower than the choir and with a slight bend in order to compensate for the steep ground. During Napoleon's occupation of Vienna in 1805, the church was used to store weapons and horses. The interior features a high, vaulted Gothic ceiling and the altar is adorned with stained glass and a winged Gothic finish.
