Wellington Pit was a colliery in the town of Whitehaven in the historic county of Cumberland in northern England. Sited near the coast, it was operated by the Whitehaven Colliery Company which sank twin shafts between 1840 and 1845 to extract coal from the 10 foot thick Main Band coal seam. The workings eventually extended four miles under the nearby Irish Sea. The buildings of the mine complex were designed by architect Sydney Smirke to resemble a castle. Little now remains beyond the 'candlestick chimney', some walls and Wellington Lodge.
