Temporary military camps set up by the Roman army. When it was on the move, this was its systematic procedure for overnight and short-stay stops. Surveyors laid out a suitable and reasonably flat rectangular site, tent positions were planned and marked, usually surmounted by a palisade of stakes. These distinctive enclosures may be identified by aerial survey. Roman marching camps exist at Culter, Kintore, and Ythan Wells in Scotland.
