Carmarthen Castle, Medieval castle ruins in Carmarthen, Wales
Carmarthen Castle is a ruined medieval castle set on raised ground above the River Towy in the center of Carmarthen, Wales. The remains include sections of stone curtain wall and two towers, all of which are Grade I listed and classed as a scheduled monument and a National Monument of Wales.
The fortress was founded in the early 12th century under King Henry I as a royal stronghold and became the main seat of royal administration for West Wales. It was attacked and rebuilt several times over the following centuries before falling into ruin during the 17th century.
The castle sits at the heart of Carmarthen and today shares its grounds with the county council offices, which gives it an unusual double life as both a ruin and a working civic space. Visitors can walk among the surviving towers while the daily business of local government continues nearby.
The ruins are in the center of Carmarthen and easy to reach on foot from the main streets. Part of the site has a visitor center, which is a good starting point before exploring the remaining walls and towers.
Edmund Tudor, the father of King Henry VII, died here as a prisoner in 1456 during the Wars of the Roses, making this Welsh castle an unlikely turning point in the story of the English crown. Without his death here, the Tudor dynasty that followed might never have taken shape in the way it did.
