commemoration day. Saint Afra's remains had been discovered in Augsburg around 1064. Henry IV was buried in the unconsecrated chapel from 1106 to 1111, when Pope Paschalis II revoked the ban, which had been in effect since 1088. During restoration works in 1971 a page of parchment was found in the chapel which is part of a Wulfila Bible written around 500. Today, the Saint Afra Chapel is a tabernacle. Initially there were five other chapels on the northern side of the cathedral: Saint Paul, Saint Agnes, Saint Bernard, Saint Henry, and Saint Mary. Saint Mary's chapel had been added on the northern side of the cathedral by Bishop Matthias von Rammung in 1475. Their ruins were already removed in the 18th century. Bells The cathedral's peal is composed of nine bells of which the larger four were cast in 1822 by Peter Lindemann (Zweibrücken) and the five smaller ones in 1963 by Friedrich Wilhelm Schilling (Heidelberg). They are all contained in the cathedral belfry, located in the western dome. In Germany, the bells are always numbered from largest to smallest, Bell 1 is always the tenor or bourdon. The four largest bells also serve as clock bells; bells 4 and 3 chime alternately every quarter hour while bells strike 2 and 1 in succession each the number of a full hour.
