Archaeologists have identified a Roman fort in Pembrokeshire, Wales, that may confirm a medieval legend about the fourth-century Roman emperor Magnus Maximus. The discovery includes fourth-century coins and other artefacts at a site near Frenni Fawr hill.

The account of Magnus Maximus establishing a military camp in the area has existed only in medieval folklore until now. Maximus ruled Britain during the fourth century and led troops against the Picts and Scots. The new finds at the fort location suggest the medieval tale had a factual basis, according to The Guardian's exclusive report.

The Guardian did not provide details about the specific artefacts beyond the coins, the size or condition of the fort, the dating methods used to confirm the fourth-century period, or statements from the archaeologists involved beyond noting their excitement at the discovery.
