Summary : A sequence of Roman forts at Castle Shaw. The first fort on the site was an Agricolan period fort, built in turf and timber circa AD 79. This was refurbished soon after construction and then abandoned circa AD 95. Within the south eastern half of the fort a fortlet was constructed, also in turf and timber, circa AD 105. This was developed during its brief occupation and then sleighted and abandoned circa AD 125. Both military sites were constructed on a spur of higher ground, known as Castle Hill, overlooking Castleshaw Valley. The Roman road from Chester to York runs through the valley and the forts were built to defend and patrol the road in this section as it approaches the western Pennines. The original fort had two ditches outside a rampart enclosing an area 115 metres by 100 metres orientated north east to south west. Within this enclosure were the 'principia' (the administrative centre), the 'praetorium' (the officer's quarters), barracks and granaries. The fortlet, although on the site of the original fort, had two ditches and a rampart of its own and enclosed an area 50 metres by 40 metres with barracks, workshops and a large granary. The Roman fort and fortlet survive reasonably well despite the damage caused by later land use and a number of archaeological excavations. Earthwork remains of the Roman road leading towards the fort survive 50 metres to the south east of Castle Hill. This was part of the road from Chester to York and another section is visible running north east from Castle Shaw Farm. |
More information : [SD 9988 0965] Roman Fort [G.S.] (1) Of the two Roman forts at Castleshaw the outer one was erected in or about A.D.80 by Agricola but was soon abandoned. The inner fort was built soon after the opening of the second century. The fort was abandoned c.AD 125. (2-3) Brief description and history. Plan [see AO/61/229/2] illustrations. (4) First and second interim reports on excavations, 1907-8. (5) Excavations in 1957(6) and 1958(7) have been carried out for Manchester University at the larger of the two Roman forts at Castleshaw ([SD] 999 096 ) ... A large amount of rusticated pottery supports and Agricolan foundation. The finds are deposited in Manchester Museum. (6-7) Saddleworth, Castle Shaw, Roman forts. Scheduled. (8) A 25" survey has been made. (9) Survey of 29.8.61 revised. The interior of the forts has been considerably disturbed by the annual excavations of Manchester University. No internal detail survives, and the rampart, also, is assuming an unintelligible form. (10) The Agricolan fort was excavated in 1964. An unexpected find consisted of a prehistoric pit containing a Beaker group (at least four vessels). (11) There are no surface indications of Thompson's excavation. (12) RIGODUNUM. From its position in Ptolemy, probably the Roman Fort at Castleshaw. (13) There are 2 superimposed Roman military works at Castleshaw. The earliest is an auxiliary fort measuring approx. 300 by 360 ft within the ramparts and enclosing nearly 2 1/2 acres. The latest is a fortlet observing the same orientation and with its SE rampart overlying that of the fort. It measures 135 by 165 ft within the ramparts enclosing about 1/2 an acre. Excavations between 1957 and 1964 established that the NW defences of the fort consisted of a turf-built rampart set on a corduroy of oak posts and 2 V-shaped ditches. On the NE the rampart was similar but without a timber corduroy and no ditches were found. Inside the fort, the western quarter was found to contain 2 granaries set end to end and bordering the intervallum road. Further west, part of a rectangular timber building was also identified. The northern quarter contained a series of parallel shed-like buildings separated by stone-paved roads. These were identified as roughly built barracks on the evidence of clay hearths. The presence of ash-pits inside the fort and rampart material in the lower half of the ditches, suggested that when the fort was abandoned the defences were partly levelled, the buildings systematically demolished and their timbers burnt. The excavations gave no reason for doubting the accepted attribution of the fort to Agricola c. 79-80 AD, or the founding of the fortlet under Trajan followed by abandonment early in the reign of Hadrian (13). Geophysical survey in 1977 located the link-road to the W. gate of the fort (14). (14-15)
90% of the early 2nd century base or commissary fortlet was exposed during excavations between 1984 and 1989. It was of two phases (as the earlier fort), measuring 1950sq metres overall in area, with double V-shaped ditches, a turf rampart on a stone foundation and 2 six-post gates on the N and S sides. The central Via Principalis aligned precisely with the same road in the underlying fort. (16)
Clarke suggested a `late Southern British (S3) Beaker domestic site of c1550+/-50bc' for the pit assemblage below the fort. (17-18)
