The Largest Castle in Wales

The largest Castle in Wales, second only to Windsor Castle in the whole United Kingdom.

The story behind Caerphilly Castle…

What’s your inspiration?

For Caerphilly Castle, the inspiration was the fear of a Welsh prince (guessimg that wasn’t your answer). Not just your average Welsh prince, but the all mighty Prince Llywelyn ap Gruffudd was the reason why Caerphilly is home to the breathtaking castle.

Although Prince Llywelyn ap Gruffudd was the castles inspiration, its true hero was Lord Gilbert de Clare’s who in 1268 quickly ordered the construction of this truly formidable fortress. The castle still to this very day stands (and leans) as the largest medieval castle in Wales.

Unbreachable walls, over glancing towers and impassable gatehouses were combined with sprawling water defences to cover an astounding total area of 30 acres. To give you an idea of the scale of Caerphilly Castle, consider that the Tower of London would fit within its outer walls twice!!👀

My personal experience…

I absolutely loved my visit to this 13th Century Castle, it was just what I imagined and more. It felt as if I was dicovering a new secret around every corner and it really transported me back in time. Everything a Medieval castle should be, it even has its very own pit of dragons (i’ll let you guys discover them on your visit).

The famous statue of the 4th Marquess of Bute, supporting up the front left leaning tower.

The Statue supporting the tower…

The 4th Marquess of Bute is sculpted by John Merrill in 2013.
His wealth & tenacity saved the castle from ruin, for the People of Wales.

4th Marquess of Bute – John Crichton-Stuart.(20 June 1881 – 25 April 1947)
The Marquess is displayed supporting Caerphilly’s famous leaning tower. The larger than life sculpture stands over 20 feet tall, & shows the 4th Marquess, wearing a long flowing robe. Sculpted from a fallen Oak, found in the grounds of Powys Castle, Mid Wales.

    1. Thank you, I would highly recommend you visit this castle when you plan that trip! Yeah the dragon pit is pretty cool! I won’t give much more away but definitely go see it, it won’t disappoint!

      I would also highly recommend an italian restaurant called ‘Restaurant Volare’ (if your’e into italian food obviously). Their food was pretty amazing!
