[2] A payment known as Peter's Pence had first been levied by the King of the West Saxons in 727, and was a tax of one penny on each family that owned lands producing thirty pence per annum; its object was the support of a Saxon College at Rome. Offa now induced the Pope to allow the pence so collected from his kingdom to be paid to the Abbey of St. Alban instead of the Saxon College at Rome. The payment was called Peter's Pence because it was paid on August 1st (the day dedicated to _St. Peter ad Vincula_), the day on which the relics of St. Alban had been discovered.
All that Offa seems to have been able to do besides repairing the church was to erect domestic buildings for his monks, who in course of time numbered a hundred. We have no record of any partial rebuilding, or enlargement even, of the church of Offa's day. From the fact that certain remains of it were incorporated in the present building, and that these were of the character generally called "Saxon," there is little doubt that the church of the monastery was not the little church erected in the fourth century over the martyr's grave, but one of later date, probably the one described by Beda as standing in his day, built in the latter part of the sixth or in the seventh century. We have no further record of this church, but we know that the ninth Abbot, Eadmer, began to collect materials for rebuilding the church; but the work was not begun until the time of the fourteenth Abbot, Paul of Caen, who was appointed by William I. So enthusiastically did he work, that in the short space of eleven years (1077-88) the church was rebuilt. The rapidity of the building was no doubt chiefly due to the fact that there was no need of hewing and squaring stone, for the Roman bricks from the ruins of the old city of Verulam were ready at hand, and the timber collected by Paul's five predecessors was well seasoned. It is said that the new church was not dedicated until the year 1115, but it is hard to believe that so long a space of time as twenty-seven years would be allowed to elapse between the completion of the building and the dedication. It is possible there may be some error in this date.
We can form a good idea of this Norman church. It was like several of the other cathedral and abbey churches built at the same time, of vast size, far grander than their prototype in Normandy, St. Stephen's at Caen. The following table gives approximately the dimensions of some of these churches:
