During the 19th and early 20th centuries the church was a very popular centre of evangelical, Protestant, and Calvinist teaching within Anglicanism.

John Piper painted an evocative picture of the bombed St Mary le Port.

All that remains of the church is the 15th-century tower, a Grade II listed building,[3] and a scheduled monument[4] surrounded during the latter years of the 20th century by the modernist buildings of Norwich Union and the Bank of England, which by the 2020s were both empty and had become semi-derelict, with further redevelopment proposed.

The remaining congregation then moved to the Chapel of Foster's Almshouses, and joined the Church of England (Continuing) in 1995.

The archive also includes records of the incumbent, churchwardens, parochial church council, charities and schools, plus deeds.
