Pontllanfraith (Welsh: Pontllan-fraith) is a large village located in the Sirhowy Valley in Caerphilly county borough, south Wales. It is situated adjacent to the town of Blackwood, with the River Sirhowy passing through both locations. The village includes the communities of the Penllwyn, Springfield and The Bryn.

History
Formerly part of Monmouthshire, it was home to a Welsh coal mining community during the early to mid 20th century, providing homes for men working in a number of local pits such as Wyllie, Penallta Colliery, and Oakdale.

The Penllwyn Manor, an old stone building which is now a public house, was originally part of the Lord Tredegar Estates and is believed to be the original home of the family of Henry Morgan.

In 1912, at the 17th Century Mill in Gelligroes, Artie Moore picked up a distress signal from the RMS Titanic using wireless receiving equipment.

Education
Pontllanfraith is home to a secondary school with a long tradition. The school was originally opened as a grammar school back in 1926 before becoming a comprehensive school in 1976. A number of former Welsh rugby union internationals attended the school, including John Jeffery and the British Lions forward Alun Pask, as did the current Glamorgan cricketer Ryan Watkins. The school was criticised in an Estyn report in December 2006 and was placed in special measures; following successful re-inspections these were lifted in March 2008.
