London Stone plaque

“London Stone. This is a fragment of the original piece of limestone once securely fixed in the ground fronting Cannon Street Station. Removed in 1742 to the north side of the street, in 1798 it was built into the south wall of the Church of St. Swithun London Stone which stood here until demolished in 1962. Its origin and purpose are unknown but in 1188 there was a reference to Henry, son of Eylwin de Londenstane, subsequently Lord Mayor of London.”
