Karl Bauer's popular book about Regensburg in history, art, culture and customs is considered the standard work on the 2000-year-old Danube city. First published in 1962, it has been repeatedly revised, improved and expanded and has since gone through six editions with a total of 40,000 copies. The new edition has now been revised and expanded by his son Peter Bauer. The author knows how to report on almost every street, every historically interesting building and every personality in Regensburg's history. A book both for browsing and an indispensable reference work.
