Palais Haus zum Stein

Towards the end of the 12th century, the Haus zum Stein was erected as a three-story Romanesque residential tower, strategically located at the southeastern edge of the then city area, directly on the city wall. A member of the noble patrician family Judd vom Stein is presumed to have been the builder. Around 1250, Eberhardus de Lapide was the owner. After unauthorized alterations and an increase in the tower's height, he came into conflict with Archbishop Christian II von Bolanden. To prevent its demolition, Eberhardus promised to bequeath the house to the Mainz Cathedral Chapter after his death, but it remained in the possession of the Judd vom Stein family until they died out around 1500. In 1657, Philipp Erwein von Schönborn, brother of Elector Johann Philipp von Schönborn, was the owner.
