The Habsburgs built Königsfelden Abbey on the ruins of the Roman legionary camp of Vindonissa. Today, the convent church with its impressive stained-glass windows is the most important surviving feature of the former Abbey.
The convent church can be explored on your own. Museum Aargau offers self-guided tours with an audio guide or digital abbey book. Take a stroll through the idyllic church complex, where Franciscan monks and Poor Clares once lived.
