In the centre of what was once a large fortress is an earthen mound with the remains of a thick-walled building on top of it, which may be all that’s left of an earlier keep. Links to Caerphilly Castle too - see plaque in the gatehouse.

It's an ancient village, outdating the nearby market town of Cowbridge, and hosting a number of beautiful historic buildings. The village is home to St Quentin's Castle, a 14th-century castle perched upon a hill, a church that dates back to the 12th-century dedicated to St John the Baptist, and an early 18th-century great house that sits along the river.

Such a beautiful place and quite an emotional and spiritual place for me. As Grace mentioned above it has a chapel. That chapel is called Penrhiw chapel, it was built in Drefach Felindre in West Wales. My father lived a very short walk from that chapel, the entire family used to worship in it and my cousin ended up preaching in it (he is alive today at 95+). My dad and his brothers all went away to fight in WW2, they would come back and find solace in 'Penrhiw' for the ones who didn't come back. It was really the spiritual fulcrum for my whole family. I guess I am lucky as every time I go to St Fagan's I can go to Penrhiw and speak to my father once more....

Caerphilly Castle has had a £5m investment into conservation and repair of the structure - from late October '22 the scaffold and sheeting that protected the works will be removed. Caerphilly Castle is the biggest castle in Wales, and second biggest in the UK. Wales’s very own Leaning Tower, even wonkier than that of Pisa — courtesy of Civil War gunpowder is probably the castle’s best-loved feature.
