Wall on Quarry edge

Quarry Wall
Location	Boston Lodge North-East side of the Top Yard
Heritage Status	Not listed but significant. Wall dates back to early days of the site.
Historical significance	2012 Conservation Statement Description:- The curved stone wall above the east end of the top yard to the south of the current access road to the yard may well have been part of a wall on one side of the junction of the roadway to Penrhyn Isaf and the road to Minffordd. Remains of a further section of wall can be seen on the other side of a ramp that could have been the original route to Penrhyn Isaf. A further small wall is across a dip further south above the site of the 1877 carpenters’ shop. To the east of it a ramp continues towards the original roadway to Penrhyn Isaf. It is believed that the ramp originally continued westwards behind the 1847 Works down to the Cob though the archway and that at some time after the roadway was diverted via the level crossing at the Halt, possibly when the corrugated iron joiners shop was built in 1877, the ramp was removed and the wall was built to protect the drop.
Urgent and Immediate Repairs required	The wall was built on top of the cliff-face against which the original Waggon Repair shop was built. As part of the project to reconstruct the Waggon Repair Shop the rock-face was scaled to remove loose rock. The face was in worse condition than expected and the wall had to be removed as it was on unstable rock.
Less urgent repairs	It is hoped to rebuild the wall further back after completion of work on the face and the Waggon Shop.
