Possibly the best known of the coalfield millerite locations, Coed Ely Colliery was opened in 1916 by The Welsh Navigation Steam Coal Co. Ltd. By 1938 there were 1,006 men employed.

Following reconstruction schemes in the 1950s & 60s, Coed Ely was linked underground and worked jointly with Cwm Colliery at Llantwit Fardre, over 5km to the east By the 1970's the collieries jointly produced 515,000 tons of steam coal a year with a workforce of 1,580 men.

Coed Ely Colliery closed in November 1986 and the site has since been landscaped.
