By 1782 the noise level from the activities of Billingsgate Fish Market had become unbearable and the large windows on the north side of the church were blocked up leaving only circular windows high up in the wall. The parapet and pediment above the north aisle door were probably removed at the same time. At some point between the 1760s and 1814 the present clerestory was constructed with its oval windows and fluted and coffered plasterwork. J. M. W. Turner painted the church in the mid-1790s.
