Pit bottom 1914
Originally the pit was called the Celynen Nos 1 and 3 Collieries and retained this name until the Celynen North was opened in 1914.
Sunk to exploit what was described as ‘the most valuable seam in the United Kingdom’ (the Black Vein). The pit had a take of 1,200 acres.
Three shafts were eventually sunk. No1 Pit to exploit the Black Vein seam. No3 Pit to exploit theOld Coal seam.No2 Pit as the upcast shaft for ventilation.
The first coal was wound in 1876.
Surface workers c.1920
Peak manpower was 1905 when 1,740 men and 200 horses were employed, with the Main East District having 110 stalls and stretching for three-quarters of a mile.
In the early days the main markets were the railways of the UK, South America, Egypt, France and Italy; later the coal markets changed to steelworks and coke ovens.
The colliery ceased production in September 1985 and was left to flood in November 1985.

Three shafts were sunk by the Newport Abercarn Company to help exploit the northern section of the ‘take’, the South shaft pit-bottom being Developd from the Celynen South Colliery.
The North and South shafts were to exploit the lower and middle coal measures, and the Graig Fawr to exploit the upper coal measures.
The South shaft being the joint upcast for both ventures.
As with all shallow pits the Graig Fawr encountered very wet conditions in its working of the Brithdir seam, worked mainly for house coal, this seam had an average thickness of 1.17m (3ft.10ins).
The Graig Fawr ceased as a production unit in October 1961.
The main seams to be worked at the Celynen North have been the Meadow vein.
Upper Three-quarter, Big Vein and the Black Vein; the most productive area being the West Black Vein
District which worked from the mid 1930’s until the late 1940’s.
Workings have reached 6.4 Kilometres (4 miles) from the shafts.
The pit produced prime coking coal with Ebbw Vale Steelworks and later Llanwern Steelworks being its major customers.
Manpower has ranged from 1,250 at its peak to 570 men on closure.
In 1982 the Colliery was linked to Oakdale Colliery and its production diverted to the Oakdale shafts.
In December 1985 the workmen of the Celynen North were transferred to Oakdale, and the pit was allowed to flood.

Two excellent books documenting the history of the Celynen Collieries have beenwritten by Colin Spencer.
