The outer gatehouse was built with a specific design that allowed the portcullis to be operated from the floor above.
The inner ward contains the remains of a great hall that was extensively rebuilt in the 14th century.
Evidence of a Norman motte-and-bailey predecessor remains visible within the stone ruins.

Kidwelly is one of the few castles in Wales where the footprint of the original medieval town is still clearly associated with the fortress.
The site was featured as a filming location in the television series Monty Python and the Holy Grail.
Kidwelly Castle is a well-preserved Norman fortress featuring an iconic concentric design overlooking the River Gwendraeth. Originally founded around 1106, the structure underwent significant expansion during the 13th and 14th centuries. The castle is notable for its 'castle-within-a-castle' layout, comprising an inner curtain wall protected by a secondary outer wall. Visitors can access the four massive circular towers and the gatehouse, which houses a small exhibition. The site offers expansive views of the surrounding Carmarthenshire countryside. It is managed by Cadw, the Welsh government's historic environment service. The masonry remains largely intact, allowing for detailed observation of medieval defensive architecture. The castle ruins are surrounded by the remains of a medieval town, including an early Norman church nearby.
