The plan was nominally an oblong square, but, owing probably to the desire of Wren to make use of the old foundations, its walls were neither built parallel nor four-square. The length was 87 feet, the height 33 feet, and the width 60 feet, of which the nave was made 48 feet wide and a north aisle 12 feet wide. To the north aisle was also attached a heavy square tower, occupying a portion of the aisle. The elevation was finished with a cornice and parapet. The tower rose above the second division from the east to a height of 86 feet. The church was celebrated for its beautiful woodwork, which, on its demolition, was removed to St. Michael Royal. Chantries were founded here by: Richard de Preston, citizen and grocer, at the Altar of St. Katherine, for himself and Agnes his wife, and to which Alfred Lyndon was admitted chaplain in 1396; Peter Cosin whose will is dated 1291 (Pat. 43 Edward III. p. 2 m. 12); Sir Nicholas Lovin for himself and dame Margaret his wife; William Lichfield, augmented by Thomas Westhowe, both of which endowments fetched £8 : 16 : 8 in 1548; and William Peston. The church formerly contained monuments to: William Lichfield, Doctor of Divinity; John Brickles, a great benefactor. Queen Elizabeth’s monument, “If Royal Vertues, etc.,” was also in this church. Two charity schools were erected in 1715, consisting of thirty boys and twenty girls supported by voluntary subscriptions from the inhabitants of the ward. Among the notable rectors of this church are: Thomas White (1628-98), Bishop of Peterborough; Hon. James York, Bishop of Ely, 1781; Robert Richardson, D.D. (1732-81), Dean of Lincoln; Edward Waddington (d. 1731), Bishop of Chichester; William Vincent (1739-1815), Dean of Westminster; William Cave, author (1637-1713). In 1877 a new vestry was built on the south side of the church. It is approached from Allhallows Lane by steps, through an arched doorway, above which stands what is called “the tower,” a mean erection and a mere apology for a tower. Its height does not extend beyond the church roof. The vestry is fitted with the panelling and the pedimented doorway brought from the old north aisle, from which also come the two fantastically and beautifully carved wooden shields, now placed respectively over the fireplace and the door. The ceiling is a neat piece of panelling. The room is used for the holding of the Dowgate wardmotes. The churchyard (south of the church) is much higher than the lane at its side. It contains one tree, several tombs, and in the north-west corner the vestry-room. The enclosure remains an open space even after the demolition of the church.
