rubble of the cloister was removed in 1820 in order to create some open space. Later it was fitted with a roof to prevent further deterioration. The sculptures were supplemented by a local sculptor, Gottfried Renn. Inside the mount is a chapel dedicated to the Archangel Michael. In the square at the western end of the cathedral is a large bowl known as Domnapf (lit.: 'cathedral bowl') It formerly marked the boundary between the episcopal and municipal territories. Each new bishop on his election had to fill the bowl with wine, while the burghers emptied it to his health. Heidentürmchen (Heath Tower) The Heidentürmchen is a remainder of the medieval town fortifications, a tower and a section of the wall, situated a little to the east of the cathedral. It once stood right by the Rhine, at the very edge of the plateau, adjoined by some marshy area which used to be called "heath". Hall of Antiques (Antikenhalle) The Hall was built to the north of the cathedral to house the Roman findings in the cathedral area. It was erected in the Neo-Classical style and turned out to be too small for the intended purpose. Later some cannons captured in the Franco-Prussian war of 1870/71 were displayed. Today it is a memorial for the fallen of the two world wars.
