Primary Reference Number (PRN) : 05896g Trust : Glamorgan Gwent Community : Brynmawr Unitary authority : Blaenau Gwent NGR : SO2007112178 Site Type (preferred type first) : Post-Medieval Level Status : Scheduled Monument
Summary : A pair of well preserved and dated coal levels with a tramroad connection to the Clydach Railroad.
Description : "A pair of well preserved and dated coal levels with a tramroad connection to the Clydach Railroad. The levels were owned and operated by the Brecon Boat Company, the principal trader on the Brecknock and Abergavenny Canal, to which the Clydach Railroad was completed in 1795. The Brecon Boat Company was granted permission to build a branch from Clydach Bridge to their new colliery nearby on 19 November 1812, at a cost of ?75. The line was built across part of the River Clydach, which was diverted through a tunnel to allow free access to the two level mouths. The tunnel for the river, the tramroad embankment, and the two levels are still clearly visible. Both levels are open and can be seen to be rock cut and unlined, but that further to the east was refronted as part of the retaining wall of the Merthyr, Tredegar and Abergavenny Railway in 1862. The scheduled area is bounded by the top of the embankment on the north and by the boundary fence of the railway to the south. Of national importance as well preserved examples of dated early coal levels with an associated tramroad formation and river tunnel." FO:"The entrance to the eastern level (Level I, SO 20071 12178) is a stone-built arch some 5.0m wide and 1.5m high with a modern safety grill. The site currently flooded. The entrance to the western level (Level II, SO 20029 12252) is 4.0m wide and 1.5m high. The level is cut into the shale outcrop and dips steeply to the south. The level is almost completely filled by collapsed roof material." (01)
