Given the question: Read the following paragraph and extract the answer for the question: Where in the castle was the last room that was completed by Burges's brother-in-law, Richard Popplewell Pullan?  In the early nineteenth century, the original Norman castle had been enlarged and refashioned by Henry Holland for the 1st Marquess, the 3rd Marquess's great-grandfather. The 2nd Marquess occupied the castle on visits to his extensive Glamorgan estates, during which he developed modern Cardiff and created Cardiff Docks as the outlet for coal and steel from the South Wales Valleys, but did little to the castle itself, beyond completing the 1st Marquess's work.  The 3rd Marquess despised Holland's efforts, describing the castle as having been "the victim of every barbarism since the Renaissance", and, on his coming of age, engaged Burges to undertake rebuilding on a Wagnerian scale. Almost all of Burges's usual team were involved, including Chapple, Frame and Lonsdale, creating a building which John Newman describes in Glamorgan: The Buildings of Wales as the "most successful of all the fantasy castles of the nineteenth century." The central block of the castle comprises the two storey banqueting hall, with the library below. Both are enormous, the former to act as a suitable reception hall where the Marquess could fulfil his civic duties, the latter to hold part of his vast library. Both include elaborate carvings and fireplaces, those in the banqueting hall depicting the castle itself in the time of Robert, Duke of Normandy, who was imprisoned there in 1126–1134. The fireplace in the library contains five figures, four representing the Greek, Egyptian, Hebrew and Assyrian alphabets, while the fifth is said to represent Bute as a Celtic monk. The figures refer to the purpose of the room and to the Marquess, a noted linguist. The decoration of these large rooms is less successful than in the smaller chambers; much was completed after Burges's death and Girouard considers that the muralist, Lonsdale, "was required to cover areas rather greater than his talents deserved."The central portion of the castle also included the Grand Staircase.
