Kidwelly Castle is an imposing Norman castle overlooking the River Gwendraeth and the town of Kidwelly, Carmarthenshire, Wales. This ruin is in the care of Cadw (historic Wales). Although it saw much conflict the castle is in fairly good condition Kidwelly began in the early 12th century as a Norman ‘ringwork’ castle made of wood and protected only by an earthen bank and ditch.

Under constant attack by Welsh princes, it was captured by Lord Rhys in 1159. Decades later the Normans were in charge and by the 1280s it had been transformed into the stone castle we see today.

The first scene of Monty Python and the Holy Grail was filmed on the walls of Kidwelly.
