Claim: Caergwrle Castle, first referenced in the rolls of the Royal Wardrobe (referencing that Llywelyn had sent 100 marks to Daffyd on 12 November 1278 towards the castle), has notable features including two D-shaped towers and a great circular keep overlooking the approach to the south-east.
Evidence: The first reference to the castle appears in the rolls of the Royal Wardrobe, referencing that Edward had sent 100 marks to Daffyd on 12 November 1278 towards the castle, however there is debate between scholars whether this was to aid the initial construction or to help in the upkeep of an already extant building.
