This is the smallest parish church in London, secluded on a narrow lane near the junction of King William and Canon Streets. It dates to the twelfth century or earlier. Because it is located quite near to Pudding Lane where the Great Fire started (now marked by the Monument), it was one of the first to be destroyed. It was rebuilt by Wren in 1683–87. The church once stood on Eastcheap, the main shopping street, when that thoroughfare ran further west. The interior, whose walls are irregular, is distinguished by a pleasing ornamental ceiling.
