The subterranean charnel chapel of Holy Trinity Church in Rothwell, Northamptonshire houses one of only two remaining in situ medieval ossuaries (collections of human bones) in England. The Rothwell Charnel Chapel Project aims to further understanding of charnelling practices in the medieval period, gain insight into the role of human remains in medieval Christian religious practice and explore the relationship of Rothwell’s current community with this unique and compelling part of their heritage.
