The Church of St Dunstan was originally constructed around 1100 and is a Grade I listed building. A new south aisle was added in 1391 and later repaired in 1631. It suffered significant damage in 1666 during the Great Fire of London.

The church was again heavily damaged during the Blitz of 1941, though Wren's tower and steeple survived the bombing. Following World War II, the Anglican Church chose not to rebuild St Dunstan’s. In 1967, the City of London decided to transform the church's remains into a public garden, which officially opened in 1970
