All Hallows by the Tower: 1,300 Years Beside the Tower

Story

All Hallows by the Tower does something remarkable on a City walk: it allows you to move chronologically backwards from modern London towards the beginnings of the Christian city. The church was founded in 675 by Barking Abbey, around three hundred years before the Tower of London. A Saxon arch still survives in the building, while the crypt contains a second-century Roman pavement discovered in 1926. Its position beside Tower Hill also brought it into contact with darker episodes. After executions on the hill, some beheaded bodies were brought here temporarily; the church’s history includes figures such as Thomas More, John Fisher and Archbishop Laud. In 1666, when the Great Fire began nearby in Pudding Lane, All Hallows narrowly survived. Admiral Penn helped organise its defence, while Samuel Pepys watched the fire from the church tower. William Penn, future founder of Pennsylvania, had been baptised here. The church was badly damaged again during the Second World War and rebuilt. If it is open, the crypt is the key: one descent reveals Roman, Saxon, medieval and modern London almost on top of one another. If closed, the stop still works from Byward Street, with the Tower of London almost opposite and Tower Hill beside you.

What to look for

The Saxon arch, the Roman pavement in the crypt and the visual relationship with Tower Hill and the Tower of London.

Secret detail

It predates the Tower of London by about three centuries and preserves Roman remains beneath a church of Saxon origin.
