Eisbach on its tributary, the Rodenbach. Not until 1309 was his coffin transferred to Speyer. In the cathedral Aldolphus was laid next to his former rival, Albert, who had been murdered in 1308 by his own nephew. For the city of Worms the Stadt-Eisbach was of great importance, not so much because it provided drinking water - there were numerous wells in the city for that purpose - but because it provided industrial water that was needed by its mills, tanneries and dye works. Whether the Stadtbach already existed in Roman times or was diverted during the Middle Ages from the original course of the Eisbach is still unclear today. In the 19th century the laying out of the Stadtbach was variously ascribed to Charlemagne or Worms Church. The Stadtbach was first mentioned in 1016, when Bishop Burchard gifted three mills near St.Paulus Immediately on the Eisbach, on the Rhine side of the Roman city wall, lay the castle of the Salian dukes of Worms, which was demolished in 1002 in order to build St. Paul's on the same spot. The castle, "one of the oldest in the Rhenish-Hesse-Palatine region", was supposed to be very heavily fortified. This strongly suggests that it may have been a water castle, although there cannot have been a moat on its eastern side. On the site of the castle there had previously been a Late Roman fortification dating to the 4th century, probably a castell for the protection of the Roman harbour that lay outside the walls. Sovereign rights over the Stadtbach belonged in the High Middle Ages to the Bishop. In the late 12th century the Stadtbach was owned in equal thirds by the churches of St.Paul, St.Martin and by several citizens of Worms who, sometime between 1198 and 1217, sold their share to Nonnenmünster Abbey (the Maria-Münster). The city council tried in the 14th century to gain sole rights over the Eisbach and in 1315 obtained a privilege from King Louis of Bavaria, that the diversion of streams within the city would attract a heavy fine. In 1381, the city obtained a further privilege from King Wenzel, whereby it was given the rights over all the streams that flowed through the city and its suburbs. If the city felt its use of the waters of the Eisbach was restricted they even used force. In 1443 for example, the citizens of Worms destroyed
