St Mary’s Church, Aldermanbury, originally situated in the City of London, was designed by Sir Christopher Wren after the Great Fire of 1666. The church was destroyed during the Second World War, but its surviving stonework was later shipped to the United States and reconstructed at Westminster College in Fulton, Missouri.

Over time, the relocated church began to show signs of wear. The stonework had weathered and cracked, with biological growth affecting the façade. Mortar joints had deteriorated, while rust was visible on metal fixtures. Rainwater goods were failing, protective glazing on windows was damaged, and nearby trees were causing root pressure and organic staining to the surrounding surfaces.

Our team’s conservation strategy focused on preserving the church’s original fabric using traditional, historically accurate methods. On each of the columns, stone surfaces were gently cleaned, and lime-based mortars were used to repoint joints. We replaced and treated corroded metal fixings and rainwater goods. London Stone Conservation was also responsible for restoring the lettering of the commemorative plaque, and enhancing visitor experience by restoring the pavement outside the church.
