Located on the floodplain of the river Towy, immediately below Dynevor Castle, is the site of a firing range which was in use during both the First World War and the Second World War.
Although the range was already present in the mid-nineteenth century and appears on the first edition OS County Series 6? and 25? maps (see NPRN 413339), by 1906 it had undergone significant changes. The OS second edition 6? and 25? maps indicate a firing line aligned roughly east-west, between the two earlier alignments, and the position of the targets (again on the east) a short distance to the north of their previous location.
At SN60992173 is shown a structure annotated `Butts? at the front, and `Targets? at the rear. This structure is a brick and concrete bunker-like building at the foot of the steep slope of Castle Woods, its location indicated on modern maps by a pronounced kink in the fence line. The building is now densely overgrown. It is rectangular with a wide rear entrance into a space measuring 5.8m (N-S) by 3m. The overall height is about 2.4m. Its rear wall projects a further 4m-5m to the north. The roof of the building is inaccessible due to dense overgrowth but may have supported the targets. Cast iron brackets project from the rear and may have been part of the target mechanism, the markers accommodated in the bunker. This building may be a more recent structure replacing the one shown on the 1906 map. To the immediate south-east (at SN61002171) is a low rectangular, dished, mound measuring 5m (NW-SE) by 2.5m and 0.3m high surrounded by a shallow ditch 1m wide and 0.1m deep but absent on the north-east side. Its purpose is unclear and no structure at this point is indicated on modern maps; it may represent the foundations of a marker's shelter, or 'mantelet', from an earlier phase in the history of the range.
The 25? map shows a 600 yard long firing line, as far as the river bank, on which the 200 yard, 500 yard and 600 yard positions are marked, with a box-like structure (shooting stand?) depicted at 500 yards; no ground traces were noted at any of these locations. The range appears on the post-war national grid County Series 6? map and is thought to have remained in use until the 1960s.
