The Welsh retook the castle in 1163, only to have Henry take it back in 1165.
Oops! He lost it once more in 1187, to Owain Fychan. Owain was then slain treacherously in a night attack by his cousins Gwenwynwyn and Cadwallon.
The English were back in 1194, and this time they built a stone curtain wall to improve the defences.
In 1197 the English handed the castle back to the Welsh voluntarily, in exchange for Gruffudd ap Rhys, an ally who had been taken prisoner. In 1212 Robert de Vipont rebuilt the castle, but it was finally destroyed for good in the 1230s, probably by Llewelyn ap Iorwerth.
The sizeable earthworks, which measure about 27 metres long by 13 metres wide, were probably much larger than they are now.
