Carmarthen Castle
Carmarthen, Carmarthenshire
There was a Norman castle here as early as 1094, though perhaps in a different location. By 1105 the current castle occupied its perch on an outcrop above the River Tywi. The original motte was augmented by stone defenses in the early 13th century. The curtain wall was added later in that century, and a gatehouse and south-west tower in the 14th century. Carmarthen was sacked by Owain Glyndwr in 1405, and later passed to Edmund Tewdwr, father of the future Henry VII. In the late 18th century the castle was converted to use as a prison.

Carreg Cennan
Carreg Cennen Castle

Carreg Cennen Castle
In Trapp, near Llandeilo, Dyfed
A 13th century ruin atop a sheer cliff, Carreg Cennen is one of the most dramatically sited of Welsh castles. Its a stiff climb, but worth it just for the atmosphere. The site may well have been used by the Romans, as finds of Roman coins and even earlier skeletons have been made here. Lord Rhys (Rhys of Deheubarth) built a more permanent castle here in the late 12th century, though it was later taken by Edward I of England in 1277.

The Welsh castle was rebuilt in impressive style by John Giffard. Several towers and portions of the curtain wall still stand, albeit in a crumbling state. much of the interior buildings have been badly damaged, a result of military action in the Wars of the Roses. One unusual feature of Carreg Cennen is the natural limestone cave beneath the castle, reached by walled passage.

The castle is sited on a hilltop overlooking the Tywi valley, providing wonderful views. Legend tells that the first castle at Dinefwr was built by Rhopdri Mawr in the 9th century. That early fortress may have been dismantled at the orders of Llewelyn the Great and the present stone castle built in the early 13th century.

Dinefwr passed to the English crown in 1276. A large round keep stands within a curtain wall, and a round tower in the north-west of the inner ward also survives relatively intact, while some of the residential buildings within the inner ward have been partly restored.
