The excavation of a ditch to bury an electrical cable has led to the discovery of a medieval church wall at St Ffinan's Church in Anglesey, England. The original church, believed to have been built in 620 CE, was mostly destroyed when the newer church was built in the 19th century.
In addition to the wall, workers found human remains dumped in a pile outside the medieval wall. These remains are thought to have been buried in the old churchyard and removed by the construction of the Civtorian church. The remains have been reburied.
