What is "all-hallows-the-great"

All-Hallows-the-Great was a church in the City of London, located on what is now Upper Thames Street, first mentioned in 1235. Destroyed in the Great Fire of London of 1666, the church was rebuilt by the office of Sir Christopher Wren. All-Hallows-the-Great was demolished in 1894 when many bodies were disinterred from the churchyard and reburied at Brookwood Cemetery.
