Crumlin Navigation Colliery

Navigation Colliery closed in 1967 although the buildings remain as the best preserved colliery complex in south Wales. It was built between 1907 -1911 by Partridge Jones & Co and is of unusual architectural quality, constructed in the main of red brick with yellow brick pilasters. The complex includes two winding engine houses, a fan house, a magnificent chimney, a pumping house, stores and workshops, powder store and baths. Behind the buildings the steep incline of Mark Phillips' tramroad can be seen. The sinking of the two shafts commenced in 1907 and was completed in 1910 to the Black Vein (Nine-Feet) seam. The downcast (North) shaft was 466 yards deep to the Black Vein. It was circular with a diameter of 20 feet and was the coal/materials/men winding shaft. The up cast (South) shaft was the same depth and diameter. The cages were single deck with two trams each with a maximum winding capacity of 700 tons per shift (North Pit). An unusual facet of this colliery was that blue pennant stone was used to line the shafts, this very expensive item being justified by the fact that virtually no repairs needed to be carried out during their working life.
