Despite the major restoration of the Beauchamp Tower carried out under the direction of Anthony Salvin in the 1850s, by the early 1900s the stonework was already starting to decay. A report of 1911 stated that the type of stone used by Salvin to reface the tower was unsuitable for London’s climate. As this drawing made in 1924 shows, part of the wall on the tower’s west front was bulging outwards due to insufficient bonding – a sign of the challenges faced by the custodians of such a historic building.
