The IRA bomb in London in 1994 did major damage to one of the few remaining medieval churches in the City. We were called in immediately afterwards to advise on the salvage of the debris, including sorting damaged stone and timbers, and ensuring that they were stored carefully. The Museum of London Archaeology Service were contracted to monitor the salvage operation and undertook the initial sorting and selection of debris. This work resulted in the preliminary identification of the building's medieval and later fabric which included 12th-century stonework, and 15th-century masonry and timbers from the roof and bell tower which formerly stood at the west end of the church. The Museum has since been commissioned to analyse the salvaged material in order to inform future restoration work.
