The interior of the church is almost square. It contains twelve Corinthian columns, placed at the angles in groups of three, and supporting an entablature prolonged to the walls by means of pilasters. There is a clerestory above, pierced on its four sides by semicircular windows. The tower, which rises at the west, contains the doorway in its basement story; the cornice is surmounted by a pedestal supporting composite columns, and the summit is divided into two turrets with balustrades above. The north front has three niches, each enclosing two Ionic columns on pedestals; the south front is plain. Chantries were founded here by: Gregory de Rokeslie, Mayor of London, 1275-81, for himself and Amicia his wife, to which John de Pory was admitted chaplain, July 15, 1333; Thomas Noket, for himself and for Alice, wife of Gregory de Norton, called atte Shire, at the Altar of the Blessed Virgin Mary and St. Anne, in the south side of the church, to which William Weston was admitted chaplain, January 28, 1400-1401; the endowment fetched £13 : 6 : 8 in 1548, when William Wentors, or Ventrys, and Richard Browne were chaplains; Henry Brige, Knt., whose endowment yielded £13: 13 : 4 in 1548, when John Meres was priest. Sir Hugh Brice, keeper of the King’s Exchange under Henry VII., was buried in this church; he built a chapel here called the “Channel”; also Sir Thomas Ramsey, Lord Mayor in 1577; William Hilton, Merchant Taylor and Taylor to Henry VIII., and Sir Martin Bowes, patron of the church for over thirty years. Among the later monuments, Stow records one in memory of Sir William Phipps, who discovered a sunken Spanish ship in 1687 containing silver to the value of £300,000 sterling, and one commemorating Sir Thomas Vyner, goldsmith, and Mayor of London, who died in 1665. The list of legacies and bequests was too long for insertion, Stow says, but was to be seen by any one in the Parish Book. He records a gift of £1 : 6s. per annum from Sir Nicholas Rainton, and one of £3 : 15 : 8 paid by the Merchant Taylors. Richard Rawlins (d. 1536), Bishop of St. David’s, was rector here; also John Newton, author of “Olney Hymns.”
