It's often interesting to delve into differing beliefs. A visit to St. Laurentius is a good way to experience one of the local religions.
You'll have sightseeing choices galore when visiting Roedelsee. St. Laurentius is a great place to begin here, but there are numerous other interesting places to check out. Muensterschwarzach Abbey, Schlosspark Schwanberg, and Weingut Hans Wirsching are close to the house of prayer and will top off your day nicely.
