Excavations at the Roman fortlet on the Antonine Wall at Watling Lodge, 1972-4 by Davi BreezdJ e SUMMARY Excavations between 1972 and 1974 at the fortlet at Watling Lodge discovered in 1894 located the single ditch surroundin site established gth ean d tha fortlee th t t measured abouy b S tt 15-N- 5m 18-5 m E-W internally. The ditch had silted naturally and no evidence was found to suggest that the defences had been slighted when the fortlet was abandoned. Finds were too few to establish the date of abandonmen sitee th .f o t INTRODUCTION e fortleTh t Watlina t g e AntoninLodgth n o e e Wall lies half-way betwee e fortnth f o s Falkir Rougd kan h Castle astrid roae eth d branching leadin d ofMilitare an fth y g ythrougWa h the Wall to Camelon and forts further north (NGR NS 862797).

The essential part of the report reads: 'Mr Buchanan observed that the whole area consiste masa f f tumbleo do s d stones, with scattered heap f brokeo s n browd nan grayis whitisr ho h pottery ease tTh . boundesids ewa stona y db e bottoming, exactly lik pavine eth g unde Vallume rth , whic directln hra y south fro Vallue mth abour m feetthe0 d fo 10 an ,nt westward, where it was soon broken up; there could hardly be a doubt that it ended on the west, as it begun easte th ,n formino grectanglea whicf o , nortVallue e hth th hs mside wa tha d Buchanar ,an M t n had added another Wall-Fort, or Castellum, to those already known.' This note was elaborated by Sir George Macdonald in The Roman Wall in Scotland (1934, 343-7): 'the stone foundation of the rampart seemed to stop short on either side of the opening, and that similarly the ends of the Ditch on either side of the roadway appeared to taper gradually and naturally to the level.... A little distance to the east of the outlet of the road, the workmen laid bare 100 feet of stonework, about 15 feet broad, very like the base of the Rampart. At first it ran due south at right angles to Limese th .

No plan appeared in the Camelon report and Mungo Buchanan apparently drew the sketch at Macdonald's request for inclusion in The Roman Wall in Scotland (1934, 345, nl). f onlo ye fortlee threon Th s i te thae knowe betweear tli o nt n paire th f forto sn o s Antonine Wall; a fourth fortlet is known to have preceded the fort at Duntocher (Robertson tn Nen i o CA O I> i KIRKINTILLOCH GLASGOW BRIDGE CADDER r WILDERNESS PLANTATION E ANTONINTH E WALL BALMUILDY I KILOMETRES i FlGl mo 16 | 8PROCEEDING THF SO E SOCIETY, 1972-4 1957, 16-33) and it has been suggested that a fifth may lie immediately E of the fort at Rough Castle (RCAMS 1963, 100). The other two 'interval fortlets' are at Glasgow Bridge between Kirkintilloch and Cadder (St Joseph 1955, 86) and at Wilderness Plantation between Cadder and Balmuildy (Wilkes 1973, t clea51-65)no s ri whethet .I r these fortlet parcomplete a f sar o t e series along the Wall, one falling between each pair of forts or whether they are only found at certain points purpose fortlee On . th f t Watlinea o t g Lodg undoubtedls ewa guaro yt roae dth d passing through the Wall, but it has been suggested that all three interval fortlets were specially placed to break up unusually long distances between certain forts (Robertson 1957, 29). The following table demonstrates that the known fortlets fall into three of the six longest gaps between forts on the Wall and, if that is indeed their function, it might be expected that others will be found.
