Nothing is known exactly as to how much of the building was completed by 1100. Professor Freeman points out that eleven years was quite long enough for its building, and that there is no hint in the local chronicle of any additions being made to the building dedicated in 1100. Probably part of the church was finished for the dedication, such as the presbytery, choir, the transepts, the Abbot's cloister, the chapter-house, and the greater part, at any rate, of the nave. The nave, though so different in scale as compared with the original choir, must have been built very early in the twelfth century, and, like the rest of the building, originally had a wooden roof. In 1101 or 1102 damage was done to the building by fire, notably the chapter-house, and again in 1122. Possibly in this latter fire the nave roof was destroyed, and of this fire the piers in the nave show traces. Of the same date must be much of the strengthening masonry in the crypt, the Prior's lodging, the chapel, and the slype beneath it. The whole of the Abbey buildings were surrounded by Abbot Peter with a stone wall, and the necessary gates--viz. the great gatehouse on the west, another on the south, and a third more to the east. All these can be identified from the small plan of the monastic buildings, reproduced (p. 103), by permission of Mr F. S. Waller. The Saxon Chronicle tells us that in 1122, while the monks were singing mass, fire burst out from the upper part of the steeple, and burnt the whole monastery. Some time between 1164 and 1179 one of the western towers, probably the south-west tower, fell down. Fire in 1190 is said to have destroyed the greater part of the city, as well as almost all the buildings in the outer court. Helias, the sacrist, also made new stalls for the monks in the choir. Of these Early English stalls, a fragment has been thoughtfully and carefully preserved behind the seat of the Canon in residence. In 1222 we learn from Hart, i. 25, that the great eastern tower was built under the direction of Helias of Hereford, the sacrist. Of this tower no traces now remain. Helias built his superstructure on the Norman work that we see in the nave. The Early English Lady Chapel was said to have been built between the years 1224-1227 by Ralph of Wylington, and Olympias his wife, and endowed with lands. The church was dedicated again in 1239, in Abbot Foliot's time, by Walter of Cantelupe, "the patriot prelate who, six-and-twenty years later, stood by Earl Simon on the day of martyrdom at Evesham."
