To provide for the maintenance of St. Paul's, Ethelbert endowed it with a farm at Tillingham in Essex. The property is still managed, the rents of which are controlled by the Dean and Chapter.
The chief event which took place within its walls was the first great Ecclesiastical Council of the English Church under the presidency of Archbishop Lanfranc. Twelve years afterwards, in 1087, a great conflagration completely destroyed the church. No time was lost, for apparently in the same year building operations were put in hand for what many writers call Old St. Paul's, the second church. By this time we may take it that architecture in England had advanced considerably, and if anything it was a rather fortunate accident that overtook Ethelbert's building. The nation had by now realised that 1000 A.D. was the dreaded millennium of the past; they recognised they had a stern master in William the Conqueror, who, though he might be harsh upon them, would allow no one else to be so. For some years prior to the millennium few buildings of any importance were erected, so thoroughly had the mind been terrorised at the prospect of the world coming to an end, and even after it had proved false, the reaction does not seem to have taken place till the accession of the Norman. When it did occur, we see by examples now extant what a great advance architecture had made, or rather, the knowledge of stone-work had become more general. This can only be attributed to the monks and stonemasons who followed in the wake of the Conquest. The plan of the Norman church of St. Paul's was the Latin cross. The body of it appears to have been narrower and considerably longer than Wren's cathedral. In fact we are much indebted to the numerous discoveries of Mr. Penrose, and we learn that the west front came right to the fore of Queen Anne's statue, which then did not exist. Another great difference was that the axis of Old St. Paul's, as one faces the west front, was more to the left of the statue, whereas that of the present building runs right through the centre of it. At the outset the Cathedral consisted of a nave of twelve bays, transepts, and a short apsidal choir built in the round arched style peculiar to Norman architecture. The whole then stood within spacious precincts enclosed by a continuous wall. In the wall were six gates. The principal one opened in the west on to Ludgate Hill, whilst the second, at St. Paul's Alley, led to "Little North Dore"; the third, at Canon's Alley, showed the way to the north transept door; the fourth was called Little Gate, and led from Cheapside to Paul's Cross (where now stands a fountain); the fifth, St. Augustine's Gate, faced Watling Street; and the sixth was the entrance from the side of the river to the south transept. A matter of 130 years later, it was decided to extend eastwards from the choir and introduce the newly developed style, which was the use of the pointed arch. The new work, consisting of eight bays, was carried out, but it caused the demolition of the old parish church of St. Faith, which lay right in the course. As some compensation the parishioners were allowed to use a portion of the crypt under the new choir as their parish church. After the Great Fire much controversy arose. The parishioners of St. Faith's claimed their right to bury their dead in the whole space beneath the choir of Wren's cathedral. This the Chapter disallowing, a lawsuit ensued, which resulted in a compromise, the parishioners being satisfied with rights of burial in the north aisle of the crypt. The "new work" was solemnly dedicated in 1240. In the meantime a spire, 489 feet in height, was put in hand and was finally completed in 1315. The spire of Old St. Paul's proved to be a great source of anxiety. It was struck by lightning three times, and eventually was completely destroyed by fire, from a fourth lightning in the reign of Elizabeth, in 1561. It was never put up again. Right in the angle of the south transept and the nave existed a fair-sized Chapter House, which appears to have had cloisters, the remains of which can still be seen in the gardens on the south side of the nave, whilst on the north side of the choir the position of Paul's Cross is defined by the insertion of stones let into the ground. Paul's Cross, which by order of Parliament was demolished in 1643, was a pulpit of wood, mounted upon steps of stone, and covered with lead. At this place, the Court, the Mayor, the Aldermen, and the chief citizens used to assemble to listen to sermons from the most eminent divines, who were appointed to preach every Sunday in the forenoon. It was used as early as 1259, and not only were sermons delivered from it, but also political and ecclesiastical discourses were held.
