St Vitus' Church sits in the old centre below Kufstein Fortress, which means many visitors pass it on the way to the bigger sight. The church has medieval roots, but much of what you notice inside is later, with Baroque decoration softening the older structure.
It is worth a short stop rather than a special trip. Step in while wandering the lanes around the lower town, then look back up to the fortress: the pairing of parish church and castle is a neat summary of Kufstein's old civic and defensive life.
