For centuries, people have been discovering Roman finds in Ffrith. Underneath the current village lies a Roman settlement, believed to have been civilian, but with links to the XXth legion. The settlement was also on a Roman road, which runs parallel to the B5101. Back in the 1960s, the remains of a Roman bath house were discovered.

Channel 4's Time Team programme has visited the village, and spent three days excavating, trying to get to grips with the area's Roman heritage. Archaeologists discovered a silver Roman brooch and red clay pottery known as Samian ware. It's believed that the artefacts will eventually be donated to the Flintshire Museum Service.

Ffrith is rich in history, with Offa's Dyke visible just outside the village (inside the village it's been flattened, but the course is along the B5101). Despite its strong historical background, it appears that Ffrith only became an established settlement in the 19th century. It is also close to a rich supply of lead, which has added to the village's industrial significance.
