What contains an ornately carved fireplace?  Answer the above question based on the context below:  In comparison to other rooms within the castle, Lord Bute's Bedroom, sited above the Winch Room, is relatively small and simple. The original plan had Bute's personal accommodation in the Keep but the expansion of the Drawing Room to a double-height room in 1879 required a late change of plan. The bedroom contains an ornately carved fireplace. Doors lead off the room to an internal balcony overlooking the courtyard and to the bretache over the gate arch. The furniture is mainly by Chapple and post-dates Burges, although the washstand and dressing table are pared-down versions of two pieces – the Narcissus Washstand and the Crocker Dressing Table – that Burges made for his own home in London, The Tower House.This bedroom is also less richly ornamented than many in the castle, making extensive use of plain, stencilled geometrical patterns on the walls. Crook suggested this provided some "spartan" relief before the culmination of the castle in Lady Bute's Bedroom but Floud considered the result "thin" and drab in comparison with the more richly decorated chambers. The bedroom would have been impractical for regular use, lacking wardrobes and other storage.
The answer to this question is:
Lord Bute's Bedroom
