From the 8th to 12th century, besides various Mainz monasteries, Saint Alban's Abbey (also in Mainz – not to be confused with the one in England, which is actually consecrated to another saint) held the most important properties in Zornheim. After the Lords of Bolanden had transferred sovereignty over Zornheim to one of the Counts of Hohenfels about 1220, the fiefholders then sold the village and the court of Zornheim to Saint Clare's Convent at Mainz ("Mainzer Kloster Sankt Klara") after receiving Count of Hohenfels Hermann II's leave to do so. In the sale document issued at Oppenheim on 9 June 1329, the selling price is named: 200 pounds of Hellers.
