 This formed the best place to bridge the Thames and the area became an important part of Londinium, owing its importance to its position as the endpoint of the Roman London Bridge.Two Roman roads, Stane Street and Watling Street, met at Southwark in what is now Borough High Street.Archaeological work at Tabard Street in 2004 discovered a plaque with the earliest reference to 'Londoners' from the Roman period on it.
