Summary :
Watching brief at Chepstow Castle (GGAT 94/075) produced four areas of archaeological material, these being predominantly masonry in composition.

Description :

During this Watching Brief on the excavation of a cable trench, excavated by Swalec, within the scheduled area of Chepstow Castle, four areas produced archaeological material.

The first was located south of the Lower Bailey and consisted of collapsed masonry with attached mortar. This is most probably the result of collapse from the damaged wall of the Lower Bailey that is currently supported by two buttresses.

The second area was located below the central tower of the Middle Bailey. A masonry wall was identified lying directly underneath the north edge of the current tarmac footpath. Neither the structure or the finds identified a use for this structure.

The third area consisted of a layer of crushed mortar located at the base of the trench, south of the Great Tower. No other features were identified with this structure and no finds were retrieved
from the context.

The last area was located west of the south west tower of the Barbican. A bank is currently visible on the ground and it is believed that this represents the location of a portion of the missing town wall. A large quantity of stone was identified within this
portion of the trench, but no mortar or other material was associated with it.

Phillips notes that Chepstow Castle (also known as Striguil) comprises a large masonry edifice on a natural rock outcrop with no evidence of a motte or an earth/timber construction built on the site. He notes that it is one of the first, if not first stone built castles in Wales and has masonry of Roman origin within the original structure. He suggests that the castle’s position on the river provides an offensive military location guarding the port and waterway into Wales (Philips 2004).
