The priory was suppressed, and the great nave was deliberately pulled down. But, except that so much of the cloister as adjoined the nave was destroyed with it, no further demolitions took place at that time, and it was only gradually that the conventual buildings, some of which lasted to our own day, were removed. The choir and transepts were preserved to form a parish church, and the area of the destroyed nave became the churchyard. The rest of the buildings were sold by the King to Sir Richard Rich, for the sum of L1,064 11s. 3d., not a large sum considering the area of the site and the extent of the buildings, which included, among others, the prior's lodgings, styled "the Mansion," which had housed so great a man as Prior Bolton. [Illustration: FIG. 6--PRIOR BOLTON'S WINDOW.] In Queen Mary's reign the Church resumed possession of the conventual buildings, and they were occupied by the Black Friars, who, it is said, made some attempt to rebuild the nave; but beyond some slight works to be seen in the east cloister, they left no traces of their occupation behind, the sole relic remaining of them being the seal of their head, Father Perryn, the matrix of which has already come into the possession of the church authorities. With the death of Mary the friars retired, and the choir became, once more, the parish church, and for the next century neglect and decay continued the ruin of the fabric. But with the advent of Laud to the See of London, some attempts were made at reparation. It is said that the steeple had become so ruinous that it had to be taken down, and in 1628 the present brick tower, which stands over what was the easternmost bay of the south aisle of the nave, was erected. Where the ruined steeple stood is not clear, but most probably over the crossing, and as towers were unimportant features in the churches of the Austin Canons, it is likely that it rose but little above the roofs. Another and remarkable erection of this period was the charnel-house at the east end, known as "Purgatory," which was constructed with some attempt to give it a Gothic appearance, and was attached to the reredos wall. This is shown in fig. 7, which illustrates the eastern ambulatory, as it existed before the restoration. [Illustration: FIG. 7--EASTERN AMBULATORY AND PURGATORY BEFORE RESTORATION.]
