The plain exterior is in contrast to what John Betjeman called an "exalting" succession of features inside. The interior has wooden galleries supported on square panelled columns, a semi-circular apse with a half dome, a highly decorated plasterwork ceiling, and, at the east end the only 18th century stained glass window in the City of London, a depiction of "The Agony in the Garden" painted by James Pearson. The stained glass in the aisles is partly Victorian, and partly from the 1940s. Some monuments were preserved from the old church, including the tomb of Anne Packington, who died in 1563. The organ, in a gallery at the west end, is by Samuel Green and dates from 1788.
