The church was dedicated to Saint Botolph or Botwulf, a 7th century East Anglian abbot and saint. By the end of the 11th century Botolph was regarded as the patron saint of boundaries, and by extension of trade and travel. The veneration of Botolph was most pronounced before the legend of St Christopher became popular amongst travellers. There were four churches in London dedicated to Botolph, three outside the city gates at Aldersgate, St Botolph-without-Bishopsgate and St Botolph's, Aldgate. A fourth, St Botolph Billingsgate was near the waterfront wharves and London Bridge. St Botolph Billingsgate was destroyed by fire in 1666 and not rebuilt. The location of these churches at the edge of London reflects all three aspects of Botolph's patronage.
History
Medieval church
The church was founded before 1291. The earliest recorded rector is John de Steventon in 1333. The living was originally in the possession of St Martin's-le-Grand, but on the dissolution of the priory King Henry VIII granted it to the bishop of the newly founded Diocese of Westminster. The patronage eventually passed to the dean and chapter of Westminster Abbey. During the Middle Ages there was a hospital for the poor outside Aldersgate. A Cluniac foundation, it was suppressed by King Henry V as an alien house, and its lands and goods were granted to the parish of St Botolph. The medieval church was a Gothic building, divided by arcades into nave and aisles. There were three gables at the east end. In 1627, the steeple was rebuilt in Portland stone, with battlements and a turret, and the rest of the church repaired. Many of the pews were replaced, and a new clock and dial were installed. The improvements cost, in total, £415. The medieval church was long and wide. The 17th-century steeple was about high, and contained six bells. In an account published in 1773 the church is described as having galleries on the north and west sides, oak pews, and a carved oak pulpit.
Eighteenth-century rebuilding
The church escaped the Great Fire of London with only minor damage, but, having become unsafe, was demolished and rebuilt in its present form in 1788-91 under the supervision of Nathaniel Wright, surveyor to the north district of the City of London. The new church was built of brick, with a low square bell tower at the west end constructed on the remains of its stone predecessor. 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 centurystained 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. The east façade, towards Aldersgate Street, is a screen wall, erected in 1831 and executed in Roman cement, with a pediment and four attached Ionic columns standing on a high plinth, with a Venetian window between them. The church underwent several restorations during the 19th and 20th centuries, and many of the furnishings are from the late 19th century. From the mid-1980s the church was restored by Caroe & Partners. Work on the east front was completed in 2008.
Currently, St Botolph's, Aldersgate is used by the London City Presbyterian Church, a congregation of the Free Church of Scotland, that meets there every Sunday. During the week, the building is used for lunchtime services, under the auspices of St Helen's Bishopsgate, Church of England. It is also the rehearsal venue of the .
