What is "normandykes"

Normandykes (Grid Reference: NO 830994) is the site of a Roman marching camp to the southwest of Peterculter, City of Aberdeen, Scotland. The near-rectangular site, measuring approximately , covers about of the summit and eastern slopes of a hill overlooking the River Dee and the B9077 road further south. Aerial photographs for Normandykes have been archived between 1947 and 1976. The camp is about , or less than half a day's march, north of the Raedykes camp. It is possible that the actual route taken would have entailed one day's march, over a route likely chosen to avoid the Red Moss, a virtually uncrossable bog near the present day village of Netherley. Normandykes was first excavated in the year 1935 by Richmond and MacIntyre; construction is thought to date to the Antonine or Severan periods.
