The altar came to be placed at the head of the cross. The transept, crossing it at right angles, formed the arms, and the nave the upright.

The altar was always situated at the east end, again illustrating a link with the pagan times, when worshippers turned towards the sun.

As time progressed chapels were erected along the sides, causing the walls to be pierced and arched. These chapels were in honour, firstly, of "The Blessed Virgin," and then of the leaders of "The Faith," who had been canonised as saints on account of martyrdom. But the main building was always dedicated to the "God Head."

By a special grant in 1154, given by Pope Adrian IV., who was born near St. Albans, and who was the only Englishman ever appointed to the Papal See, the abbots of St. Albans were allowed the privilege of wearing a mitre. Added to this dignity he was given precedence over all in England, whether they were king, archbishop, bishop, or legate. He also exercised supreme episcopal jurisdiction over all clergy and laity in all lands pertaining to the monastery.

The first abbot was Willgod, nominated by King Offa.

The last one was Richard Boreman, otherwise Stevenache.

In all there were forty-one from the foundation to the suppression, which took place in 1534. In that year the monastery was seized by Henry VIII., who allowed pensions to the monks, and an annuity to the abbot.

About 1480 the abbey was amongst the first in England to set up a printing press. On this the first English translation of the Bible was printed.

In spite of every loving care exercised, the relics of St. Alban enjoyed little rest. In Wulruth's reign as fourth abbot, the abbey suffered at the hands of the Danes. They carried away with them the bones of "the Proto-martyr" to Denmark, and there placed them in a convent at Owenses. They were found and brought back to the abbey.

Again, seventy years later, the Danes ravaged the country. But this time Ælfric II., eleventh abbot, resorted to artifice. He hid the bones in the walls of the church, and sent bogus relics to the monastery at Ely, giving the monks special charges to guard them well. On the retirement of the Danes from the country, Ælfric sent post haste to reclaim these bones. Ely at first demurred, but, giving way in the end, sent back some substituted bones. This disquieted the saint.
