Excavations at Caerlaverock Castle, 1955–66

Abstract

The acceptance of Caerlaverock castle into guardianship was followed by consolidation of the masonry and the clearance of the silted moat. In parallel with these operations, a series of excavations was carried out to investigate the nature of the outer defences and any surviving evidence for earlier bridges. Four different phases of timber bridges had crossed the moat to the gatehouse; the first three were dated by dendrochronology to 1277, 1371 and to the second quarter of the fifteenth century. An outer earthwork, originally intended purely to retain the water of the moat, was remodelled in the sixteenth century as an artillery defence. The approach to the castle was remodelled with an additional rock-cut moat, crossed by a timber bridge dated by dendrochronology c. 1559–94. Documentary evidence is examined for the use of these artillery defences, especially in the final siege of Caerlaverock in 1640. A rich assemblage of finds was recovered, mainly from unstratified contexts, both from the excavation of the bridges and from the general clearance work of the moat.
