Pentre Berw is a small village located on the island of Anglesey, in north Wales. It lies two and a half miles south of the county town of Llangefni.

A major road, the A5, runs through the village as does the disused Anglesey Central Railway. Indeed the village's most famous hotel The Holland Arms even had a station named after it. The village is located at the top of a gentle slope on the eastern edge of the Malltraeth Marshes. Therefore a good view of the marshes and also of the Afon Cefni can taken in from parts of the village.

Plas Berw, a country house which dates back from the early 17th century, is near the village. It also has formal gardens and a deer park. The grounds cover some 8.5 acres (34,000 m²) and it is a Grade II listed building. Llanfihangel Ysceifiog (St Michael's church), although ruined, is a good example of a traditional Welsh church. It is situated just north of the village.

Pentre is a village and community, near Treorchy in Rhondda valley, falling within the county borough of Rhondda Cynon Taf, Wales. The village's name is taken from the Welsh word Pentref, which translates as homestead, though Pentre is named after a large farm that dominated the area before the coming of industrialisation. The community takes in the neighbouring village of Ton Pentre.

Pre-1850, the area which is now Pentre was made up of several scattered farms tended by tenant farmers for absentee landlords. With the discovery, in the early 19th century, of economically viable coal deposits in Dinas Rhondda it was not long until expeditions reached the mid valleys. In 1857 Edward Curteis of Llandaff leased the mineral rights of Tyr-y-Pentre from Griffith Llewellyn of Baglan and soon had two levels opened, the Pentre and Church. During the early part of 1864 deeper shafts had been sunk by the Pentre Coal Company. The mines in the Pentre were some of the most profitable of all the collieries in the Rhondda.
