Caerphilly Castle
Visitor Notice
Cadw has announced details of an investment of £5m in development works at Caerphilly Castle ― a project designed to strengthen the site as a world-class heritage attraction by 2023.
All part of a wider £9.5m investment into Wales’ historic sites, the funding boost will see the 13th-century castle benefit from an extensive programme of conservation, site access improvements, and a complete overhaul of site interpretation.
Opening times
To ensure visitor safety, we are currently opening the castle from 10.30am Monday–Friday and 9.30am Saturday and Sunday; this is to ensure our monument is safe and ready to open as fully as possible whilst our contractors are working in and around the castle.
Overview
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.
