A marching camp that is about 190 x 107 m.
This is a so-called Stracatho style marching camp and is thought to date to the Agricolan campaign of 82-83. These camps include Dalswinton, Castledykes, Menteith, Dalginross, Ythan Wells, Auchinhove and Inverquharity. All of them have distinctive double clavicula protuding entryways. The right clavical projects outward in a straight line, while the left one projects in an arc. This type entry was first observed at the Stracatho Marching Camp.
