Pontlottyn, initially part of Lower Rhymney, was born and grew from the enterprise of the coal and ironmasters and as many as thirty-one pits and levels existed between these two villages before 1835. This industrialisation brought a huge increase in population with rural Welsh workers and particularly Irish immigrants flowing in, attracted by the promise of rich earnings from the growing iron industry. It was well known for its neighbouring
collieries, which employed nearly the entire local population in the early 20th century.
George "Honey Boy" Evans was born here, in 1870.
Edward Thomas Chapman, a miner who won the
Victoria Cross during
World War II, was born at Pontlottyn in January 1920. ==Facilities==
