Regensburg

Regensburg| or |}}}} (historically known in English as Ratisbon, ) and Italian, Spanish, and Portuguese ''Ratisbona'' – as a cognate of its Latin name of ''Ratisbona'', which is in turn derived from Gaulish ''Radasbona''.}} is a city in eastern Bavaria, at the confluence of the rivers Danube, Naab and Regen, Danube's northernmost point. It is the capital of the Upper Palatinate subregion of the state. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremberg and Augsburg and the eighth-largest of all cities on the river Danube. From its foundation as an imperial Roman river fort, the city has been the political, economic, and cultural centre of the surrounding region. Later, under the rule of the Holy Roman Empire, it housed the Perpetual Diet of Regensburg.

The medieval centre of the city was made a UNESCO World Heritage Site in 2006 because of its well-preserved architecture, being the biggest medieval city site north of the Alps, and the city's historical importance for assemblies during the Holy Roman Empire. In 2014, Regensburg was among the top sights and travel attractions in Germany. Provided by Wikipedia
