In 2003 a Roman road was reported to pass just north of village. The road originates from the major Roman town of Carmarthen, known as Moridunum during the Roman period. The destination of the road is uncertain and has only been traced beyond Wiston for a mile or two.[4]
In 2013 it was confirmed that about 500m north-east of Wiston near Churchill Farm, is located the first ever Roman fort discovered in Pembrokeshire.[5]
The site is shown on the Ordnance survey county series as a U-shaped quarry approximately 170m in length. This is a significant discovery that shows the Romans did indeed travel into Pembrokeshire. Dating appears to indicate that the fort is 1st century with possible 2nd century occupation. It remains to be seen whether there are further forts to the west, possibly at St Davids.
Medieval presence
The medieval presence at Wiston includes Wiston Castle[6] and the church, St Mary Magdalene. There has been a church on this site at least since c1147. The current structure was founded by Wizo the Flemming (also responsible for the castle). The church is a typical Norman church with a square tower.
Governance
An electoral ward exists. This ward stretches beyond the confines of Wiston community. The total population of the ward at the 2011 election was 1,973.[7]
