Newbridge Chainworks Canal Basin on the Glamorganshire Canal

A canal basin of snecked rubble walls and flat dressed copings, oriented roughly N-S. The basin opens out on both sides. On the W side the level of the towpath descends gradually from N-S. The S end has later concrete slab copings, while the towpath is laid with later concrete. An outflow culvert near the N end has a dressed stone surround, immediately S of which is a butt joint defining the widening of the original canal to create the basin. On the E side the wall is visible only on the northern half of the basin, as a later retaining wall is built over the remainder. The E wall is clearly of 2 phases as an earlier coping course is visible in the wall below the present coping level.
