Known as the ‘Cathedral of the Wachau’, the large baroque parish church boasts colourful frescoes by Martin Johann Schmidt, an 18th-century local artist who was also known as Kremser Schmidt and occupied a house from 1756 near the Linzer Tor in Stein. The baroque building is the work of Cipriano Biasino who worked on several churches in the Wachau, including the abbey church at Stift Göttweig.
