The vivid Marktplatz (market place) in the midst of the Altstadt is surrounded by the Neues Schloss, the Stiftskirche, the Dampfbad and the Friedrichsbad. Under the pavement there is the Roman "Kaisertherme" (baths of the emperors), whose outlines can be easily seen by the dark markings on the pavement. There are several festivals taking place here both in the summer- and in the winter-time.. . The catholic church on the Marktplatz is called Stiftskirche. The lower, Roman parts of the tower date from 1220-40. The Gothic sections were erected between 1453 and 1474. The church was badly damaged by the Great Fire in 1689. It was rebuilt in Baroque-style between 1751 and 1753, Gothic amendments were made in 1866-67. Restoration work was carried out in 1954 and 1967/68. Of historical interest is a crucifix by Nikolaus Gerhart von Leyden (1467), a tabernacle (around 1500), the tombs of the margraves of Baden from 1391 to 1793 and a monument to Margrave Ludwig Wilhelm known as Louis "the Turk" (1753). . The Alte Dampfbad (old steam bath), the three story building in toscany-style, was erected in 1846-48 by Heinrich Hübsch. Today various exhibitions are being shown in the building. . The Rathaus (town-hall), built in 1632, was rebuilt after the Great Fire of 1689. Since 1862 the building with the escutcheon of alliance Baden-Lauenburg at its entrance gate serves as the town-hall to the city of Baden-Baden.
