This medieval church was destroyed, along with most of the churches in the City, by the Great Fire in 1666. In 1670 Parliament passed a Rebuilding Act and a committee was set up under the stewardship of Sir Christopher Wren to decide which churches would be rebuilt. All-Hallows-the-Less was not amongst those chosen; instead the parish was united with that of All-Hallows-the-Great, and the site of the church retained as a burial ground.
