The trigger for development of the site at Arnulfsplatz 195b was provided by businessman and bicyclist Simon Oberdorfer. He hired the young architect Joseph Koch for planning. Founded in 1891, the building first served as a hall for various cycling demonstrations for the Wanderer-Radler-Verein (Walking & Cycling Club) including artistic cycling presentations by Oberdorfer himself. In the course of planning, the idea developed to build an event center. The approval dragged on, as the city magistrate repeatedly criticized the unfavorable fire escape situation due to close quarters. Only action by Adolf Schmetzer on October 1, 1897 brought the breakthrough to obtain preliminary approval. Nevertheless, there were still a few legal pitfalls waiting. It was not until 1898, after a short construction period, that the opening took place. Initially the Velodrom was used for many classical events with variety, dance and artistry demonstrations. Part of the variety program was artistic cycling by so-called "eccentric-cyclists", even bicycle races were included. So in fact the building at least partially served the initial purpose and justified its name. The hall was also rented for major social events. Thus, it was also used in 1904 for the General Assembly of German Catholics (51st Catholic Day). In addition, Oberdorfer hosted Social Democrats, who had no other meeting place in church-dominated Regensburg.
Georg von Vollmar,
Kurt Eisner, Erhard Auer and Toni Pfülf also spoke here. The building was renovated according to strict monument preservation criteria from 1990 to 1996. In addition, remains of a Roman house were discovered during the excavation work. After installing modern seating, the building will henceforth be used as an event hall. ==Structure and equipment==
