For anyone planning to travel to south Wales, Cardiff Castle is well worth a visit.
Literary Link: Cardiff Castle is featured, albeit briefly, in my current read - Susan Higginbotham's Hugh and Bess (synopsis from Chapters.indigo.ca:

Just as walls break down and love begins to grow, the merciless plague endangers all whom the couple holds dear, threatening the life and love they have built.
Award-winning author Susan Higginbotham's impeccable research will delight avid historical fiction readers, and her enchanting characters will surely capture every reader's heart. Fans of her first novel, The Traitor's Wife, will be thrilled to find that this story follows the next generation of the Despenser family.
