Germany - Old town of Regensburg with Stadtamhof

"Located on the Danube River in Bavaria, this medieval town contains many buildings of exceptional quality that testify to its history as a trading centre and to its influence on the region from the 9th century. A notable number of historic structures span some two millennia and include ancient Roman, Romanesque and Gothic buildings. Regensburg’s 11th- to 13th-century architecture – including the market, city hall and cathedral – still defines the character of the town marked by tall buildings, dark and narrow lanes, and strong fortifications. The buildings include medieval patrician houses and towers, a large number of churches and monastic ensembles as well as the 12th-century Old Bridge, which dates from. The town is also remarkable for the vestiges testifing to its rich history as one of the centres of the Holy Roman Empire that turned to Protestantism."
