The church of St Martin Pomeroy, sometimes known as St Martin Ironmonger Lane, is of medieval origin although the date of its founding is uncertain. The name “Pomeroy” could be a reference to the apple trees (French: Pomme) that grew nearby or a link to the Pomarys family. It was sited halfway down Ironmonger Lane, right next door to the church of St Olave Jewry. Indeed, these two churches were less than 30 feet apart and shared the same churchyard.
We have some idea what the church looked like from the Copperplate Map of 1555. Sadly, it was destroyed in the Great Fire of London of 1666 and the parish was combined with St Olave Jewry. It was not deemed worth rebuilding two churches so close to each other.
The church building may have been lost but the parish remained. So you can still find some physical remnants of the church’s existence in the parish boundary markers shown in the photos. Use the parish map to help locate them in Frederick’s Place, Ironmonger Lane and King Street.
St Olave Jewry was to suffer a similar fate when it was demolished under the Union of Benefices Act in 1887. Only the church tower was kept which is now an office building. When the plot was redeveloped, the human remains from the combined churchyards of St Martin Pomeroy and St Olave Jewery were reinterred in the City of London Cemetery on the outskirts of London in Manor Park. If you visit you will find the handsome monument shown in the photo.
