Glamorgan (Scotch) Colliery, Llwynypia.

Between 1861 and 1862 Mr. Begg sank the first two pits at Llwynypia, to the Rhondda No2 & 3 bituminous seams, for the Glamorgan Coal Company, which was formed by Archibald Hood.

Hood purchased Trealaw colliery and he renamed it Llwynypia No.3. Nos.2 and 3 were used for winding and No.1 was the upcast.

In the early 1870's another two shafts were sunk to the steam coal measures. No.4 for pumping and No.5, which became the upcast for No.3. Later No.6 was added. 

No.3 pit worked the No.3 Rhondda seam and the coal it produced supplied the collieries coking plant, where high quality "Hoods Coke" was manufactured. Later when the No.3 Rhondda seam became exhausted, a level was driven close to the No.5 pit to work the No.2 Rhondda seam.

The colliery was also famous for making bricks from the clay mined at No.3 pit.. Women using hand moulds produced up to 10,000 per day.

From the Inspector of Mines list 1896, No.3 produced House coal and fireclay and Nos.1, 2 and 6 produced steam coal employing a workforce of 2,331 in total.

It became part of the  Cambrian Combine Company 1907, and was the scene of violent clashes during the Tonypandy riots of 1910/11.

In 1913 the number employed here had increased to 3,907.

By 1918 No.3 had ceased production and was maintained for pumping only. At this time there were 3,156 employed at Nos.1,2 6 and Sherwood level.

From a list 1923, there were 2,372 men employed at Nos.1,2 and 6 and 27 at the Sherwood level, with a further 532 surface workers. Coal was produced from the Two Feet Nine, Four Feet, New Six Feet, Five Feet, Lower Five Feet, Bute and Pentre seams. At this time No.3 "water course only".

An explosion occurred at this colliery on the 25th of January 1932, which killed 11 miners, including two members of the rescue party.
