A Roman fort at Wiston in Pembrokeshire has been previously suggested, but it was not until analysis of Lidar data that firm evidence was obtained. This was followed up in 2012 by a geophysical survey which further strengthened the case for a fort at Wiston. Geophysical evidence was not conclusive, but it seemed to show classic 'playing card' triple-ditched fort. Trial excavation in 2013 demonstrated that the site is a Roman fort. Examination of the pottery suggests that the fort was occupied in the late first century/early second century AD and that it was reused in the mid-second to the mid-third century AD, perhaps as a civil site.1.
The fort is locatied approximately 50m to the north of the remains of a Roman Road 2.
