Arnulfsplatz is a central square in Regensburg . The square in the west of the old town and north of the theater was only created in 1803 from a large predecessor square, when the master builder Emanuel Herigoyen had completed the construction of a theater and society house on behalf of Prince Primate Dalberg . This theater building, called the New House, divided the large square that existed at the time, together with today's Bismarckplatz , and two squares were created. Today, six thoroughfares lead to Arnulfsplatz north of the theater, as well as a pedestrian passage to the Velodrom theater venue and access to an underground car park.
