Rick Edwards and Beau Ouimette look for evidence of Roman life in Scotland, heading to Ardoch Fort in Perthshire, on the east bank of the River Knaik. It spans over eight and a half acres and was built under Agricola around 80AD on the east bank of the River Knaik. The fort occupied a key strategic route through Perthshire and into north-east Scotland from the First to Third centuries.
