What is "durno"

Durno or Logie Durno, located north west of Inverurie in Aberdeenshire, Scotland, is the site of a Roman marching camp, first discovered by aerial photography in July 1975 and excavated in 1976 and 1977.

With a total area between and , it is the largest Roman camp that has been found north of the Antonine Wall. The exceptional size of the camp at Durno has led to it being suggested as the place where Agricola assembled his forces before the Battle of Mons Graupius in AD 84, though the evidence for this has been criticised as largely circumstantial.

The camp was enclosed by a ditch wide and deep. The south west side of the camp was long, and the north west side long.
