Roman London Wall Remains

Remains of the old Roman Wall and modern office premises in St Alphage Garden. The wall once formed the boundary of the ancient city of Londinium - but is now with the 21st century Square Mile of the City of London, the capital's financial district, on 27th June 2023, in London, England. The Roman wall was built between 190 and 225 as a defensive ragstone wall around the landward side of the city. The London Wall was one of the largest construction projects carried out in Roman Britain, requiring somewhere in the region of 85,000 tons of Kentish ragstone to complete.
