Cadw's description

Location

At the rear of the main terrace and extending N of the Colliery Chimney.

History

Navigation Colliery Crumlin was built by the firm of Partridge Jones and Company between 1907 and 1911. The firm was one of the largest coal combines in S Wales, owning 9 collieries in the Gwent valleys. Navigation Colliery was a show-pit of the period with high quality buildings and up-to-date machinery. One of the earliest collieries in S Wales to be built in brick rather than local stone with brick dressings. Closed 1967 and disused since.

Exterior

A long narrow building subdivided into stores and shops for colliery services such as carpenters, smiths and fitters. Of high quality red and yellow engineering brick, the yellow brick used decoratively, projecting and stepped at eaves, plinth and quoins, with narrow pilasters separating the units. Former Welsh slate roof now mostly lost. Matching round-headed openings to doors and deep windows with narrow keystones; these formerly had multipane metal-framed glazing, similar overlights to doors, now partly lost. From N, units are of 4 bays, 3 bays, 5 bays and 7 bays. 5-bay unit has 2 lateral chimneys and one at end with a large ventilator. Gable end has gable roundel, two round-arched windows.

Interior

Bolted metal trusses to roof and walls of yellow brick; doorways led to lobbies.
