Administrative / Biographical History

Cymmer Colliery is situated in Porth in the Lower Rhondda Valley. The mineral rights for the colliery was leased by George Insole and his son, James in September 1844. The same year they opened the South Cymmer Level to the No. 2 Rhondda Seam. This was followed by a the No. 1 (Old Pit) shaft in 1847. During the 1850s, Insole sank two further pits on Cymmer land; these were the Upper Cymmer Pit (1851) and the New Cymmer Pit (1855). In 1856, the Cymmer Colliery was the site of one of the worst mining disasters in Wales when 114 miners were killed.

Insole and Son became a registered company in 1869. The Colliery remained an independant concern under the same family ownership until closure in 1940.
