St Michael, Cornhill, is a medieval parish church in the City of London with pre-Norman Conquest parochial foundation. The medieval structure was lost in the Great Fire of London, and replaced by the present building, traditionally attributed to Sir Christopher Wren. The upper parts of the tower are by Nicholas Hawksmoor. The church was embellished by Sir George Gilbert Scott and Herbert Williams in the nineteenth century.
The church escaped serious damage in the Second World War and was designated a Grade I listed building on 4 January 1950. In 1960 the Victorian polychrome paintwork was replaced with a more restrained colour scheme of blue, gold and white. A new ring of twelve bells, cast by Taylors of Loughborough, was installed in the tower in April 2011. The church has one of the oldest sets of churchwarden's records in the City of London, which are now kept in the Guildhall Library.
