The best preserved medieval city in Germany, Regensburg in southeastern Bavaria presents a perfect combination: an inviting skyline, impressive historic monuments, and legendary hospitality. Catholic travelers will especially want to visit the gorgeous Rococo church "Zu unserer lieben Frau" (Church of Our Dear Lady). St. Peter's Cathedral bears testimony to the grandeur of the medieval era in which some of the most important historic buildings in Germany were built. A trip for a mass and choir performance at the Niedermünster Church should also not be missed.
