One Angel Lane, formerly known as Watermark Place, replaces Mondial House, a redundant international telephone exchange in the heart of the City of London, on a riverside site next to Cannon Street station. The site has an important place in the history of the Thames and is defined by the working river. The northern edge boundary is also the line of the Roman riverbank, and the ‘Steelyard’ under Cannon Street station was a Hanseatic trading post, the largest medieval trading post in Britain.
