The footpath beyond the boathouse was closed in Nov 23 due to being unsafe and was still closed in January 2024 when I visited.

The memorial at the Castle celebrates Gwenllian, one of Wales's greatest heroines. In 1136 she led a Welsh army against Marcher lord Maurice de Londres. The battle took place nearby and despite her bravery Gwenllian was captured and beheaded. Gwenllian was a princess by birth and marriage. Her husband, Gruffudd ap Rhys, was prince of Deheubarth; her father, Gruffudd ap Cynan, Prince of Gwynedd. King Henry I died in 1135. With no heir, England was left in turmoil. Sensing the chance to win back lands, the Welsh launched a campaign against Anglo Norman rule. Gruffudd travelled to Gwynedd to gather support. With her husband away, Gwenllian led her doomed army against a Norman counter attack. Gwenllian and Gruffudd's greatest legacy was their youngest son, The Lord Rhys, who rose to become the most important Welsh ruler of the time.
