Pen-y-cae-mawr is a small hamlet above the Wentwood Forest in Monmouthshire, Wales. It lies about 2miles east of Llantrisant.
There are two farms, Cas-Troggy and Penyrheo, and a Methodist chapel on the main road. The chapel recently celebrated its 121st anniversary. Services are held on the second and fourth Sunday of the month at 3.00pm.[1] There are also the remnants of a Baptist Chapel, known as "Pen Y Well". Gravestones in the churchyard date from the 18th century.[2]
