Jane Coal Pit was sunk in the 19th in Workington. Jane Pit is the best surviving example of the ornate castellated style of colliery architecture that was a feature of the Cumbrian coal industry, the site is a scheduled ancient monument. Jane Pit closed in 1875 when pumping was discontinued after the sea broke into the mine entombing 100 miners. Apart from the fantastic engine house on site it retains a gin circle (enclosed at one time). This coupled to the engine house is a rare example of a coal mining archaeology that shows the evolution of horse-powered winding to steam power. The horse gin provided an early means of raising coal up the shaft and appears as a circular earthwork immediately to the south of the winding engine house. The engine house is well preserved and is probably one of the finest in the UK. Jane Pit can be found at NGR NX995278.
