It is the only Jacobean church to have survived in London. The identity of its architect is unknown. It has a high nave, linked with the narrow aisles by arcades supported on Corinthian columns. The church is long and wide; the height to the ceiling of the nave is . The chancel has a rose window, reputedly modelled on the much larger one in Old St Paul's Cathedral (destroyed in the Great Fire). The window and its stained glass are original, dating from 1630. The baptismal font dates from around 1640. The vaulted ceiling bears bosses of the arms of 16 of the City's livery companies and of the City of London itself. From the east end the bosses are: North Aisle – Mercers, Drapers, Skinners, Salters, Dyers and Pewterers Nave – The City of London, Fishmongers, Merchant Taylors, Ironmongers, Clothworkers and Leathersellers South Aisle – Grocers, Goldsmiths, Haberdashers, Vinters and Brewers The present scheme dates mostly from the restoration of 1972. Tradition says that these Companies used St Katharine Cree for a time after the Great Fire of London of 1666, while their own Guild Churches were being rebuilt. The church is a Grade I listed building. By the south wall of St Katharine's is a memorial to RMS Lancastria, a troopship sunk at sea with huge loss of life during the Second World War in 1940. It includes a model of the ship and the ship's bell. St Katharine's has a ring of six bells. Lester and Pack of the Whitechapel Bell Foundry cast five of them including the treble bell in 1754. Thomas II Mears of the Whitechapel Bell Foundry cast the tenor bell in 1842. The church clock has a bell, also cast by Lester and Pack in 1754. In the summer of 2007 they were rung for the first time since 1880. An appeal to raise £60,000 to restore the bells to full ringing order was launched in November 2007, and the project was completed in 2009. It is the only tower in the City where the bells are rung from a ground-floor ringing chamber. Today St Katharine's is a guild church and has no parish, but chose some years ago to dedicate its ministry to the worlds of finance, commerce and industry.
