Cwm Nant-y-Groes level.
Situated up in the Cwm-Nant-y Groes area of Six Bells. The colliery is featured on the 1843 map of the coalfield as being in production and had a tramway to the main tram road in Six Bells.
Opened by Messrs T. P. & D. Price. Mr Thomas Protheroe Price and Mr David Price were brothers, Coal Owners and Merchants of Brecon and original owners of the Tillery Colliery Penybont in the 1840s. The news item (above) is from October 1857 and proof they were the early owners the Cwmnanty Groes Levels.
Clapp & Williams had owned a level in this area in 1864.
In 1869 Cwm Nant-y-Groes Colliery and the Tillery Collieries were listed as being owned by Messrs Clapp and Williams – Clapp & Williams and Co.
At this Colliery in March 1876 Mr W. J. Clapp tested a new Coal Cutting Machine that he had invented, the machine was made in the workshops of Mr Dyne-Steel and used at Cwm Nant-y-Groes Colliery to demonstrate its use in front of many invited guests, they included the representatives from the Powell Duffryn Coal Company, Mr Lionel Brough inspector of mines, and Mr Cadman deputy inspector. The machine was propelled by steam on rails and featured a series of borers placed horizontally in a frame, the borers would drill a number of holes into the bottom of the coal face taking 6 to 7 minutes then moved forward to bore another batch of holes and so-on, the colliers would come behind and wedge out the blocks of coal. During the experimental cut the machine bored out a block of coal 6ft 2ins long, 3ft 8ins wide, 2ft 2in thick and weighing 1 ton 13cwt.
In 1896 it was under the ownership of Clapp & Co, there were 24 men employed below ground and 6 on the surface.
In 1898 it was under the control of Messrs Webb’s, Aberbeeg.
In 1908 Mr William Gay of 19 New Princess Street Abertillery was the owner and there were 6 men employed below ground and 0 on the surface. It was not listed in 1918 or after.
The tramway came across the side of the mountain North-West towards the Cwm Farm area to the White House -which was originally an engine house for the Colliery. The trams of coal were dropped down the incline which is now where Coronation Road and Eastville Road is today and down to the railway above the Coach & Horses Inn. The Inn at this time was set back against the railway about where the subway is now. In the 1870s the railway company wanted to widen the railway up through the valley from a single track to a double one to accommodate the increase in traffic. The Coach & Horses Inn was demolished to make way for this expansion and rebuilt on the side of the river bank where it is today.
In January 1931 Messrs A. West and H. Weaver gave notice that they were to re-open the Cwmnanty-Groes Levels and were given permission by the Council to access them and the air-shaft via Council property.
The waste from this level was dumped close to the levels in the valley, later the tips were flattened, levelled and made into the sports fields.
