The Tower of London is a Grade I listed structure of the greatest cultural and historic significance and a UNESCO World Heritage Site.

The Tower was built on the Thames by William the Conqueror towards the end of 1066. Its purpose was to protect London from further invasion, demonstrate his power and fully assert his claim to rule. The White Tower, from which the castle gets its name, is a wonderful example of royal Norman military architecture. Built around the central Tower is a vast complex of original buildings and later additions set within two concentric rings of defensive walls and a moat.

Working at such a busy location means that it is essential to avoid disruption to visitors and the day to day running of the site, while delivering the works on time and to the highest standards of workmanship and health and safety.

The preservation of the historic fabric at the Tower of London is an ongoing commitment requiring meticulous care and expertise. Our work includes surveys and documentation, lime mortar repairs, repointing, grouting, consolidation, as well as the dismantling, rebuilding, and analysis of stone and brick.

As part of the preventative maintenance program, London Stone Conservation has undertaken significant projects such as the consolidation of the West Moat wall, repointing of the Outer Curtain wall, and conservation and repair work on the White Tower. Additionally, we have carried out the documentation, dismantling, and rebuilding of the Well Tower.

We are honuored to maintain our longstanding partnership with Historic Royal Palaces, contributing to the conservation of these iconic landmarks and safeguarding the legacy of our built heritage.
