St Mary Moorfields is a Roman Catholic church in Eldon Street near Moorgate, on a site previously known as Moorfields. It is the only Catholic church in the City of London. Prior to a 1994 boundary change, the church was in the Borough of Hackney, such that there were no Catholic churches in the City. The present building, located at 4–5 Eldon Street, was opened in 1903, after the previous building had been demolished in 1899. However, the foundation had a long history prior to this. A chapel was opened in 1686, but was suspended in 1689, in the aftermath of the Revolution of 1688. The church serves as a hub for evangelism, especially directed at young people who work in the surrounding financial district. The church hosts monthly Opus Dei meetings, and is also affiliated with the St Francis of Assisi Ramblers. History The first post-Reformation public Catholic chapel in the City was the Lime Street Chapel set up in 1686, in the reign of James II. It was suppressed, and later re-established in Grub Street (now Milton Street), near Moorfields. The Gordon Riots of 1780 resulted in the destruction of a chapel in White Street. Following the Roman Catholic Relief Act of 1791, the White Street chapel was rebuilt. In 1817, Reverend Joseph Hunt arranged the building of a church on the east side of Finsbury Circus. The church, which opened in 1820, was designed by John Newman in the neo-classical style and given the name St Mary Moorfields, opened in 1820. In 1850 the Catholic hierarchy was re-established in the United Kingdom, and the church was chosen as London's Pro-cathedral by Cardinal Wiseman. In 1869, the title of Pro-cathedral was passed to Our Lady of Victories, Kensington. Organ The earliest known pipe organ associated with the parish dates from the second half of the eighteenth-century, and so may have been obtained for the post-Gordon-Riots chapel in White Street. This instrument is currently located in the Anglican church of St Mary Lode in Gloucester. It had previously been located in the Anglican church of 'St Nicholas, Gloucester; moved there in 1831 by the organ-building firm of Gray and Davison. The next pipe organ associated with the parish – for which there is detail – was installed around 1830 by the organ-building firm of Bevington, and was a much more substantial instrument, better befitting the 1820s building. In 1842
