This was replaced by a stone keep in 1100, and a royal palace was erected within the banks in 1130. In the meantime the first cathedral on the site was completed in 1092, but it burned down only 5 days after it was consecrated. A new, larger cathedral was completed around 1190.
Relations between the clerics of the cathedral and the castle guard were punctuated with outbreaks of petulance and occasional violence. The churchmen became so exasperated that in 1219 Bishop Richard Poore decided that enough was enough, and he determined to build a new cathedral at a location several miles to the south. A settlement grew up around the site of the new cathedral, and it is this settlement that is the modern city of Salisbury.
With the shift of settlement away from Old Sarum to New Sarum (Salisbury) the old site lapsed and the castle fell into disuse. Despite the fact that the site was derelict, Old Sarum continued to send a representative to Parliament until the mid 19th century.
