The watching brief was conducted as a series of site visits during the excavation (by hand) of the trenches and manholes. A written, drawn and photographic record of the exposed features and deposits was made. During September and October 2010 Oxford Archaeology (OA) carried out an archaeological watching brief at All Saints Church, High Wycombe, Buckinghamshire (NGR SU 86571 93089). The work was commissioned by JBKS Architects on behalf of All Saints Church PCC in advance of the installation of new toilets and kitchens. The watching brief revealed three internal brick-built burial structures of post-medieval date. The vaults contained triple-shelled wood and lead coffins. Small assemblages of disarticulated human remains, medieval tile, metalwork, animal bone and shell were recovered. The bulk of the material was redeposited, probably during restoration work in the 19th century. The exception to this were three damaged and poorly preserved medieval floor tiles, found in situ. Finds were not retained and human bone reburied.
