'Stracathro' Camps These camps are characterised by four gateways with distinctive defences, Dalswinton being firmly dated to the Flavian period. They stretch from the Dalswinton camp in Dumfriesshire to the camp at Auchinhove in Grampian.
Antonine Camps These small camps of around 4 or 5 acres all lie in close proximity to the Antonine Wall. They most likely housed the working parties engaged in the Wall's construction during the mid-2nd century.
'30-Acre' Camps Each of these camps has four gateways with titulum outwork defences. They mostly occur along the south-eastern edge of the highlands from Dunblane in Central to Finavon in Tayside, with a lone example at Bonnytown in Fife and others suspected at Bellie on the northern Grampian coast and at Inveresk on the Firth of Forth. Dr. David J. Breeze assigns all these camps to the Agricolan campaigns, on what basis I am not certain.
'63-Acre' Camps These camps all possess six gates defended by external tituli; the camp at Ardoch overlies an Antonine signal-station and therefore must belong to a later set of campaigns, probably Severan. These camps mostly occur on the edge of the highland zone in the eastern parts of Central, Tayside and Grampian, with only three examples occurring in lowland Scotland.
'120-Acre' Camps These large camps have six gateways with external tituli defences. They occur in an arc stretching along the edge of the Highlands from Ardoch in Tayside to Muiryfold near the north Grampian coast.
'165-Acre' Camps These very large camps also have six gates defended by external tituli and mark the passage of almost the entire Roman army of Britain through the lowlands of Scotland.
Marching Camp Groups Also of interest are the following groups of camps, which possibly relate to successive campaigns of Severus and his son Caracalla.
