Oriel Myrddin (The Old Art School)

This building began as an art school and is now a gallery, constructed in the Northern Renaissance style. It dates from the late 19th century, likely the 1890s. The exterior is predominantly red brick, with dressings of dark red moulded brick and Bath stone, and a hipped slate roof with a gable to the front right. It is two storeys high, with three bays, the bay to the right being wider and containing tall studio windows. A raised plinth is present, featuring a black brick top and a black brick course below the ground floor openings. Dark red moulded brick cornices run along the ground floor and eaves. The windows are ashlar, with flush sills and curved top corners, featuring small panes of glazing. The studio gable has a tall three-light window on each floor. Thin pilasters, flanked by moulded brick courses beneath the main cornices, are present on either side, projecting forward over the cornices. The eaves cornice is interrupted by the upper window head. Brick piers, with raised strips, extend to parapets, each topped with a small cornice and ball finials. Above these raised strips are brick wall panels framing ball finials over the windows. A steep pediment sits above a stone modillion course, finished with stone coping and a spearhead finial. The two bays to the left feature cornices extending across, with paired pilasters between, and an outer pier with a single pilaster on each floor. They contain two first-floor two-light windows with similar detailing (the left-most light being blank), and a ground floor two-light mullion and transom window to the left. Matching top lights are above the main door to the right, which has a depressed arched head, a recess above, and a flat sill aligned with the top lights. "SCHOOL OF ART" is inscribed in block lettering above the door, which has double three-panel doors.

The north elevation displays two large first-floor windows, each with 25 panes, breaking through the eaves under brick gables with ball finials. Ashlar window surrounds and heads are curved at the corners, with a cornice across both windows under the gables, and a panelled red brick chimney between them. The south end wall has a first-floor cross-window lighting the stair, positioned to the right, along with a single light in the centre, and a chimney to the left. A small, hipped, one-storey red brick addition dating from the 20th century is present.

The interior features a large former studio on each floor to the right, and stairs to the left. In 1892, the ground floor housed an elementary room and a modelling room, while the first floor contained a studio and a master's room. The entrance hall has a patterned tiled floor, and the lobby features half-glazed inner doors. A double arch to the left leads to the stair hall, supported by part-fluted piers with moulded capitals and big roll-moulded arches. The broad, open-well stair is constructed from pitch-pine, with a closed string, panelled newels, ball finials, and turned balusters. A large stair-light incorporates patterned coloured glass, bearing the date 1891. An arch provides access to the rear ground floor room, which features coloured quarry tiles and one moulded beam. An arch leads to the main ground floor exhibition room to the right, featuring a single cross beam and a wooden floor. Two similar arches provide access to the first floor landing.
