Regensburg, on the Danube River in Germany’s Bavaria region, boasts a colorful history that spans two millennia. Romans raised a fort here around 90 A.D., and the town grew into a prosperous trading center as early as the 9th century. Regensburg's heady mix of culture, art, philosophy, scholarship, and architecture has fueled its residents as well as stimulated travelers passing through. The Old Town (along with nearby Stadtamhof) is a UNESCO World Heritage site and often referred to as Germany’s Medieval Miracle.
