The shrine of edward the confessor: A study in multi-frequency gpr investigation

Following an earlier investigation into the 13^th Century Cosmati mosaic in Westminster Abbey, Ground Penetrating Radar (GPR) investigations were commissioned in order to locate the site of a large royal tomb. Antennas of 400MHz and 4GHz frequency were used in the area of the High Altar steps and on the floor of the current Shrine Chapel. The investigation uncovered evidence of the target tomb, a number of other graves, some previously unknown, and at least one buried object. The paper briefly discusses the frequencies selected and illustrates how these have resulted in better understanding of the archaeological and historical evidence.
