In the war between King and Parliament (the English Civil War) the city of Hereford fell into the hands first of one party, then of the other. Once it endured a siege, and when it was taken the conquerors ran riot in the cathedral and, in their fury, caused great damage which could never be repaired. In the early years of the 18th century, Bishop Bisse (1712-21), devised a scheme to support the central tower. He also had installed an enormous altar-piece and an oak screen, and instead of restoring the Chapter House he allowed its stones to be utilized for alterations to the Bishop's Palace.
