• A large section of London’s Roman wall had gone on show to the public thanks to an innovative collaboration between Urbanest, the City of London Corporation, Historic England, and the Museum of London. A new free display – The City Wall at Vine Street – has been created by Urbanest as part of a redevelopment of the site. At its heart is a segment of London’s Roman wall, including the foundations of a bastion or tower. Alongside the wall is a permanent display of artefacts from the Museum of London ranging from a tile marked with a cat’s paw print to Roman coins and ceramics. Completed between AD 190 and 230, the Roman wall was between two and three metres thick and faced with blocks of Kentish ragstone. This section of the wall was first rediscovered in 1905 when a new building – Roman Wall House – was constructed on the site and the inner face of the wall was exposed and preserved in the basement. In 1979, the outer face of the wall and the bastian foundations were also uncovered – but the wall was still left largely forgotten in the building’s basement. The site was acquired by Urbanest in 2016 and during the subsequent construction of Urbanest City in 2018, the wall was protected by a timber enclosure. Tickets to The City Wall at Vine Street, located at 12 Jewry Street in the City of London, can be booked for free. For more head to https://citywallvinestreet.org.
