LONDON, ENGLAND - SEPTEMBER 21: A skull forms part of a collection of bones that were found among the stepped footings of Westminster Abbey's south transept, on September 21, 2015 in London, England. The footings were built from Reigate stone between 1246 and1250, during the reign of Henry III, and back filled with charnel material comprising mostly of femurs and skulls from earlier burials. The square hole on the skull is likely from pick axes used to dig out the bones in the 13th century. The area is currently being excavated as part of the transform of part of the 13th-century Triforium into a new viewing and gallery area that will be open to the public for the first time. As well as exhibiting many historical objects from the abbey, the new £19m GBP space will give visitors views down over the abbey buildings and the neighbouring Palace of Westminster. The work is due to be completed by 2018 (Photo by Dan Kitwood/Getty Images)
