Historic Places in Caerphilly County Borough

Fear of a Welsh prince inspired the mightiest medieval castle in Wales Llywelyn ap Gruffudd didn’t build Caerphilly Castle. In fact he twice tried to knock it down before it was finished. But he was certainly its inspiration. The rise of the powerful Prince of Wales persuaded Marcher lord Gilbert de Clare that he needed a fortress in double-quick time. And it had better be truly formidable. So from 1268 de Clare constructed the biggest castle in Wales — second only to Windsor in the whole of Britain. Massive walls, towers and gatehouses were combined with sprawling water defences to cover a total of 30 acres. That’s three times the size of Wales’s modern-day stronghold and home of Welsh rugby, the Principality Stadium. On the death of Llywelyn this frontline fortress was transformed into a palatial home with a hunting park and northern lake. It passed into the hands of Edward II’s ruthless and greedy favourite Hugh Despenser, who revamped the great hall in ornate style. By then Caerphilly must have appeared like some mythical castle floating in an enchanted lake. An effect oddly enhanced by the Civil War gunpowder that left the south-east tower at a precarious angle. In fact Wales’s very own Leaning Tower — even wonkier than that of Pisa — is probably the castle’s best-loved feature.

Castell Morgriag is an unfinished castle ruin lost beneath undergrowth and hidden away from view,to all but the most determined castle-finder. Access to the castle is via a track that runs from a car park behind a public house where with consideration you can park your car. Unfortunately the once tendered grounds are now overgrown with brambles and thick undergrowth, making exploration very difficult to make out the castle walls and towers. I've therefore included a map to help the discovery of this ruin.

Ruperra Castle near Draethen in Caerphilly is the ruined remains of a striking early seventeenth-century semi-fortified house built in 1626 by Sir Thomas Morgan, occupying a prominent hilltop position in the forested landscape of the Gwent uplands. The castle is a remarkable example of transitional architecture between the defensive castle tradition and the more comfortable country houses of the early Stuart period, with four round towers at the corners of a rectangular block in a design consciously echoing the medieval castle form while providing more comfortable domestic accommodation. The ruin has been in a precarious condition for many years and has been at the centre of ongoing conservation campaigns. The wooded hilltop setting visible from several directions in the Vale of Gwent makes it one of the more striking castle ruins in southeast Wales, and its architectural interest as an early seventeenth-century house-castle of this form is considerable.
