Claim: Caergwrle Castle (located in the town of Caergwrle, in Flintshire, Wales), first referenced in the rolls of the Royal Wardrobe (referencing that Edward 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: Caergwrle Castle (Welsh: Castell Caergwrle), also known as Queen's Hope in scholarly texts, is located in the town of Caergwrle, in Flintshire, Wales. 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. Notable features included two D-shaped towers and a great circular keep overlooking the approach to the south-east.
