All Hallows-by-the-Tower (All Hallows Barking) is an Anglican church overlooking the Tower of London.
The church was founded in AD 675 by the Saxon Abbey at Barking and still contains a 7th century Saxon arch built from recycled Roman tiles. Works on the church also uncovered a 2nd century tessellated pavement from a domestic roman building in the church crypts.
Although the church was expanded and rebuilt several times between the 11th and 15th centuries, it was mostly gutted during the blitz due to Nazi bombing.
Its proximity to the Tower of London meant that it acquired royal connections, with Edward IV making one of its chapels a royal chantry and the beheaded victims of Tower executions being sent for temporary burial at All Hallows.
The church has a museum called the “Undercroft Museum” housed in the impressive church crypts that contains many Roman, Saxon and religious artefacts, along with a Byzantine stone relic and a plain stone altar from the castle of Richard I at Athlit in The Holy Land.
