The Python-approved castle!

Kidwelly Castle is a stunning fortress that rises high over the peaceful river Gwendraeth.

This beautiful castle has seen war in spades throughout its long life, leaving behind a remarkable legacy including heroes like Princess Gwenllian.

Part of this legacy also includes the castle appearing in one of the first scenes in the all-time classic, Monty Python and the Holy Grail. There's no doubt that it was chosen in part because of the striking sight this place imposes upon the idyllic landscape.

A castle within a castle

Kidwelly Castle was first built in the 12th-century as a much less impressive Norman fort made of wood. But as the Normans fought with the native Welsh princes for control, the castle changed hands many times.

By the late 13th-century, it had been rebuilt as the formidable stone structure you see today.

This castle was so well defended, in fact, that even the forces of Owain Glyndwr failed to successfully capture it, breaking their siege after months of trying.

As you explore these well-preserved ruins, you're sure to be impressed by the sheer size of the walls and the towers.

A place of legends

During the 12th-century, the castle saw one of its most memorable battles: Princess Gwenllian led an army to this place to fight the Norman lord of Kidwelly Castle, Maurice de Londres.

This made Gwenllian the only woman to ever lead a medieval Welsh army into battle, a true warrior princess.

While Gwenllian was defeated, her loss was not in vain: it helped inspire an uprising that would eventually kick the Normans out of Wales for good.

You'll be back for more history
