"Lost" 12th century church found in Swyddffynnon, Wales

A team of archaeologists using a geophysical survey have discovered what is believed to be Capel y Groes, a grange chapel built in 1165 and connected to nearby Strata Florida Abbey. The church was last recorded on maps in the mid 19th century and considered "lost" since that time.

In addition to the chapel, the team discovered several prehistoric sites and a medieval corn mill.
