Visitor Notice

Cadw has announced details of an investment of £10m in development works at Caerphilly Castle

During this phase of the project, the Great Hall, central courtyard and some ground floor areas of the inner ward will be closed to visitors. Upper floors and wall walks will be open as much as possible, but will require accessing historic spiral stairs.

Due to the ongoing redevelopment works, the fisherman’s walk access route from the rear of the castle will be closed from Monday 22 April for approximately four weeks. 

Our visitor toilets will be closed throughout the project, but toilets are available at the nearby Ffos Caerffili community market (closed on Mondays) just a short distance from the castle entrance. 

Venue hire and trade bookings will be considered but the site may be subject to last minute closures.

Castell Caerffili / Caerphilly Castle site map

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.
