The inscription on the top of the stone says "This is a fragment of the original piece of limestone once securely fixed in the ground now 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 there 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." The origins of this stone are intriguing and it may have represented the historic centre of London where early business in the capital was conducted or it may have served as a boundary marker. It may also have been a Roman milestone. The stone can currently (2006) be seen from inside the shop where it is located and is incorporated into the wall of the former Bank of China.
