Former Navigation Colliery Offices

Cadw's description

Location

On the S side of the colliery complex, at terrace level and rising directly from the main Revetment Wall, approached both from the terrace and by a flight of steps up the bank from S.

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

Small rectangular single storey block built in materials matching the other colliery buildings - high quality red and yellow decoratively patterned engineering brick with Welsh slate roof and overhanging eaves - but differentiated from them by a hipped roof and decorative moulded Gibbs surround in concrete to windows. Roof no longer intact; 3 tall yellow brick stacks. 6 window range facing valley, no frames survive, the cambered-arched heads with keystones; eaves band above decoratively stepped. Side elevation facing approach from Crumlin has a projecting flat-roofed porch bay with similar windows and side doorway, flanked by similar windows, very decoratively stepped eaves.

Interior

A passage lined with yellow and white brick runs through the centre of the building linking two doorways, the second giving access to the main terrrace; rooms to either side were rendered.

Reason for designation

Listed as an integral part of this important colliery complex. Group value with other listed former colliery buildings.
