Pentrebach (Welsh pronunciation: [ˌpɛntrɛˈbɑːχ], sometimes written Pentre-Bach, literally: small village) is a village in Merthyr Tydfil County Borough, Wales and is formed from the original settlements of Lower Pentrebach, Tai-bach and Duffryn.

[1] It lies on the east side of the River Taff opposite Abercanaid, south of Merthyr and north of Troedyrhiw.

His House was later used as an old people's home, and today has been converted into a Brewers Fayre Restaurant with a Premier Inn attached.

[4] Linde set up a factory in the village on a site where the South Duffryn Colliery was located.

[5] but the site has since been taken over by U.S. defence contractor General Dynamics to produce armoured vehicles for the British Army.
