St Peter's Church is an Anglican parish church in Walworth, London, in the Woolwich Episcopal Area of the Anglican Diocese of Southwark. It was built between 1823-25 and was the first church designed by Sir John Soane, in the wave of the church-building following the Napoleonic wars. It is the best preserved of Soane's churches. It is a Commissioners' church, receiving a grant under the Church Building Act 1818 towards the cost of its construction. The church cost £18,592 (£1,430,000 as of 2014), and the grant from the Church Building Commission amounted to £9,354. The church is a Grade I listed building.
It resembles two other churches by the same architect - in particular Holy Trinity Church Marylebone - in its use of London stock brickwork with stone dressings, and carries the Soane hallmark of tall arched windows set in recesses. The depressed Ionic front with cornice sand balustrade over avoids the architectural problems encountered when a pediment is used.
The east end was altered in 1888, and following wartime bomb damage, major reconstruction was carried out in 1953. The interior was re-ordered in 1982. St Peter's has always maintained a catholic tradition of worship, pastoral care and mission within the parish of Walworth, St Peter. Today, St Peter's thrives as an Anglican parish church serving the community of East Walworth. St Peter's also enjoys close links with St Peter's CofE Primary School and nursery, where the Rector is Chair of Governors.
