SN696062		 Opinion has swung back and forth on whether this is a natural collection of stone slabs or a neolithic tomb. One explanation could be that the largest stones, the 'capstone' and a supporting slab, may be in situ, but were utilised to create a tomb, possibly covered by a cairn. The site is on a broad ridge of Mynydd Carnlechert, 60m west of the Carn Lechart burial (GM078), further down the slope, and can be seen from there. 1.1 Prehistoric

SS789981		 12 km wagonway, with steep inclines to haul coal trucks over the hills from the Blaencregan colliery to the canals of the Neath valley. The construction and operating costs proved unfeasable and both Mr Parsons and his successor were bankrupted by the enterprise.

SN758073		 At Lock 17 (or 'sawmill lock') of the Swansea Canal, a dry dock was installed in 1875–6, shortly after the canal was sold to the Great Western Railway. The dry dock was alongside the normal lock, and enabled boats to be floated into place and rested on timber supports, so that the hull could be worked on after the water was emptied.

SS827926		 Dated to early 19th century, before the development of powered fans for ventilation. A brazier within the furnace building created an updraft which sucked old air out of the mine, to be replaced by fresh air via other entrances. This furnace ventilated a drift mine. It is a well-preserved example of early mine ventilation technology. 5.8 Post-Medieval/ Modern

SN772092		 Stone aqueduct built over a weir, carrying the Swansea Canal over the River Twrch. Its three massive arches make it the largest of the five aqueducts on the canal. Built in 1798 by Thomas Sheasby, it was innovative in using Hydraulic cement to line the trough instead of puddled clay. Its proximity to the Capitol Cinema gave it the local name of 'Capitol Bridge'. It was restored in 1995 but is not currently water-filled, the canal route on either side being dry. 5.8 Post-Medieval/ Modern
