Pit on three floors accesed by adit.

No trace of adit during RG visit. There is an interesting reservoir and remnants of reinforced channels to convey water for working the quarry.

Operated two water-powered mills; the later, larger mill may never have been completed. A water balance was used to raise rock from the lowest level. Peak tonnage may have approached 800 tons, but by 1890 production had dropped below 100 tons. The quarry was amalgamated with Ty’n Afallen and closed in 1908.

Public footpath from road passes processing area and then passes above pit. Active farm.
