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.

During the great Georgian period considerable work was done to the church, not without some attempt at architectural improvements, unappreciated, however, at a later date. The choir appears to have been re-roofed, the old timbers being partly re-used, but shortened by cutting off the rotten ends, with the result that the pitch of the roof was considerably lowered. To this or to their own decay may be due the destruction of the two great traceried windows at the east end, which were replaced by two wide semi-circular headed windows, which their designers, perhaps, fondly imagined to accord better with the Norman arcades below. Whether the reredos screen had already been destroyed or defaced is uncertain, or whether, as at Southwark, they were content with hacking off the projecting canopies cannot now be determined, but in place of it was erected a vast wooden structure, picturesque from its very ugliness, more suited to the classic taste of the Georgian era. At this time, no doubt, the church was re-pewed, and the great pulpit, with its sounding-board, set up on the north side of the choir.

Among the conventual buildings which had survived to this time, and remained in occupation, was the chapter house, which, with nearly all traces of its antiquity destroyed, and with a gallery erected across its west end, had been converted into a meeting-house for dissenters, the old slype having been made into a vestry. The access to it appears to have been the ancient one through the east cloister, which was also standing perfect at that time. It does not appear to have belonged to any particular sect, but was always known as St. Bartholomew's Chapel, and among those who preached in it was John Wesley, who also occasionally preached and celebrated weddings in the church itself.
