Dinefwr Castle

Dinefwr Castle

Boasting a hilltop location from which enemies could be spotted, Dinefwr Castle was the chief seat of the Deheubarth dynasty, who ruled South Wales in the 12th and 13th centuries.

Carreg Cennen Castle

Carreg Cennen Castle

Climb up for beautiful views over the River Twyi and a stunning 18th century landscaped park. Carreg Cennen - also a Deheubarth stronghold - rises out of perilously steep cliffs that pose a clear deterrent to all except the bravest marauders. It passed between Welsh and English hands during the medieval period, but bears its battle scars handsomely and was voted Wales’ most romantic ruin. Dryslwyn Castle may be the least intact, but is nevertheless commanding and atmospheric, and is considered one of the most important citadels built by a Welsh chieftain. Over at magnificent medieval Kidwelly Castle, find the memorial to Princess Gwenllian; the feisty royal died in battle, trying to save Deheubarth from Norman invaders in 1136.

National Botanic Garden of Wales

National Botanic Garden of Wales

Though only opened in 2000, the National Botanic Garden of Wales is already legendary: it has the world’s largest single-span glasshouse, is a Dark Sky Discovery Site and hosts a packed programme of annual events. Nearby Aberglasney is home to marvellous blooms year-round; appreciate them all the more knowing that the estate was on the brink of collapse when it was rescued in 1995 and hard work saw the gardens restored to glory. Fancy combining history and horticulture? Head to the Hwyel Dda Centre, whose gardens are themed around the Laws of Hywel, 10th century King of Deheubarth and, later, most of Wales.
