You can travel through time, get a crash course on making craft beer, watch high-tech robots assemble the Ultimate Driving Machine or enjoy a bird’s-eye view of the town.Regensburg is a friendly town with quaint cobblestone streets, historic Roman ruins and a UNESCO World Heritage–designated medieval city center. This unspoiled gem was the capital of Bavaria for about 700 years, from the 6th to the 13th centuries. The remnants of Regensburg’s golden age are still on display, particularly in the Stone Bridge, the first bridge to span the Danube, built in the 12th century. This bridge, which is 1,014 feet (309 meters) long, was an architectural wonder in its day. But don’t let Regensburg’s illustrious history fool you into thinking the town’s best days are all in the past. Modern Regensburg is a popular center of higher learning, with more than 30,000 students attending its various colleges and universities. In fact, Pope Benedict XVI was a professor of theology at the University of Regensburg until 1977. Regensburg also frequently appears on lists ranking the world’s best places to live, thanks to its outdoor spaces, historic city center, lively cultural and nightlife scenes, and great shopping.
