It was not the first stronghold to occupy this strategic site - it was built over the stronghold of Dafydd ap Gruffudd
, the Welsh leader crushed by Edward in 1282.
Conservationists have warned that the historic Denbighshire castle's walls, where legendary Welsh leader Dafydd ap Gruffudd
once held court, and which were later attacked by rebel leader Owain Glyndwr, are "vulnerable to collapse".
Denbigh, or little fortress, was described in 11th century records as a small border town n In 1282, Edward I conquered the town and began building a castle built over the stronghold of Dafydd ap Gruffudd
, the Welsh leader he crushed
Dim rhyfedd bod Llywelyn Fawr, Dafydd ap Gruffudd
, ac Owain Glyndwr wedi ymosod arni eto wedyn yn 1233, 1282, ac yn y 1400au cynnar.
Elizabeth de Ferres, the wife of Dafydd ap Gruffudd
, Llywelyn ap Gruffudd's younger brother, spent the majority of her married life on a succession of building sites at Ruthin and Caergwrle castles.
