Pit/Underground. Landscaped, although there is some quarry housing nearby.

Began operations around 1850 as a combination of a pit with underground workings. It experienced significant expansion during the 1860s and 1870s before entering a period of steep decline in the late 1870s. The site utilized steam haulage and locomotives for transport, and there is also a record of it employing a water balance system. Following the major industrial disputes of the early 20th century, the quarry operated as part of the North Wales Slate Quarries workers’ co-operative starting in 1903. It finally closed in 1911 after a period of joint operation with the Moel Faban and Tan y Bwlch quarries. The site was briefly re-opened in the 1920s in an unsuccessful attempt to manufacture slate powder!
