As part of the Cadw Open Doors this year Kidwelly Castle will be offering visitors free entry to explore.
Find out more about its fascinating history and architecture and take a walk around to appreciate the castle's beautiful setting.
The earliest castle on the site was Norman and made of earth and timber. By the time the 13th century had come along the castle had been rebuilt in stone, following the half-moon shape taken by the Normans.
Kidwelly benefited from the latest thinking in castle design. It had a concentric design with one circuit of defensive walls set within another, to allow the castle to be held even if the outer wall should fall. The great gatehouse was begun late in the 14th century but it wasn't completed until 1422, thanks in part to Owain Glyndŵr's efforts to stop it going up in the first place.
Tours will be at 11am, 1pm and 3pm.
