Brecon Castle Hotel

Brecon Castle Hotel is a Grade II* listed hotel featuring a stucco exterior. The north elevation showcases a central three-storey block with three windows, topped by a slate roof with projecting eaves and end chimneys. The windows are hornless sash types, with six-pane sashes on the top floor and twelve-pane sashes elsewhere. A central flat-roofed porch includes a fanlight above the door. Flanking the central block are two lower two-storey wings, each with three windows and hipped roofs made of gradated slate courses. These wings also have two dormers with hipped slate roofs and casement glazing, along with twelve-pane sash windows.

To the west, there is another similar two-storey wing with an attic, set back from the main structure, featuring a front wall that is one bay wide and tripartite sash windows on each floor. The east end of the hotel presents a three-storey gabled block that is two windows wide. A late 19th or early 20th-century wing made of stone, with half-timbered gables, extends at right angles and includes an archway leading to a former stable yard.

The south elevation faces the river and begins with a westernmost block of one bay, which features a semi-circular attic lunette and tripartite small-pane sash windows on the first and ground floors. This is followed by a three-window block with two hipped dormers, although a modern block has been built in front of it. The third block consists of a rear range to the central block, which includes a two-storey canted bay window at the west end and two additional bays to the east, all with twelve-pane sash windows. At the east end, a high projecting block has been refashioned externally in the late 19th to early 20th century, featuring two transomed and mullioned windows with architraves, entablatures, and pediments on the first floor, as well as a large bay window with a balustraded parapet on the ground floor.

Inside the hotel, there are early to mid-19th century details, including doorways with fluted architraves and angle blocks, ceiling beams, and panelled ceilings.
