Raedykes is the site of a Roman marching camp located just over 3 miles (5 km) NW of Stonehaven, Aberdeenshire, Scotland. National Grid Reference NO 842902. A marching camp was a temporary camp used mainly for overnight stops on a long route between more permanent forts, or as a temporary base while on campaign in hostile territory.
Raedykes probably dates from the late 1st century AD (Agricolan), though it has been argued that it could be Antonine (2nd century) or Severan (early 3rd century). The camp rampart (vallum) encloses the summit and eastern slopes of Garrison Hill (191m 628 ft), a prominent spur overlooking the valley of the Cowie Water, a small river draining into the North Sea on the outskirts of Stonehaven. The camp covered an area of about 93 acres (37 ha), and a computer model suggests that this would have been sufficient to house three full legions, or around 16,000 troops
The entire perimeter of Raedykes camp has been recorded, and is very irregular in shape, because of the terrain. There were six gateways of which five are visible, all protected by titulus outworks; two in the longest E side, one in the shortest S side, another in the N side and one more in the very-irregular SW side. The Mid Raedykes Farm lies inside the NW corner of the camp and Broomhill Farm lies just inside the E rampart beside the southern-most E gateway.
Raedykes is situated a day's march north from Stracathro fort (initially also a marching camp) and a few hour's march south of Normandykes.
The Roman army established a chain of forts and camps during the late 1st century AD at Ardoch, Strageath, Inchtuthil, Battledykes, Stracathro, Raedykes (probably), Normandykes, Glenmailen, Bellie, Balnageith and Cawdor. Many of these forts and camps were reoccupied during the reign of emperor Septimius Severus about a century later.
