Located on the River Danube in Bavaria, the medieval town
of Regensburg contains many buildings of exceptional quality that
testify to its history as a trading centre and to its influence on
the whole 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. The town is also remarkable for the vestiges testifying to
its rich history as one of the centres of the Holy Roman Empire
that turned to Protestantism.
