strips and muntins end in a broad plain frieze above the fifth storey separating similar but shorter windows on the sixth storey of the main block. On the central clock tower, the main entrance is a recessed pair of dark bronze doors topped by a sandstone frieze depicting sailors and dockworkers. Above it is a transom of three small four-paned windows with stone muntins. Atop the entryway is a bronze plaque with "Museum of Contemporary Art". Above the entrance, the clock tower treatment consists of three more widely separated but otherwise similar windows rising from the third storey to the sixth and topped with a decorative pink granite facade depicting a propeller, wheel, and anchor. A clock set against the sandstone is above. The tower is topped by a narrower stage, a square cupola and three flagpoles. Mordant Wing The Mordant Wing on the MSB building's north end is also six storeys high, occupying three-quarters of the remainder of the block not taken up by a local police station building. It is faced in smooth, mostly windowless panels of black, white, and brown stone, made of blocks rectilinear in shape and irregular in size. On the north end is a basement delivery entrance. The main entrance to the museum is at the southeast corner of the wing, where it abuts the MSB building at a glass-faced stairwell. Sliding glass doors in a glass two-storey entryway open onto a wide stair to the main foyer. Above it is an unsupported projecting three-storey pavilion with strip windows. North of it, a large downward-pointing arrow in the facade at ground level directs visitors to a poem carved in the concrete deck. On the west, the wing is similarly faced, with an alleyway leading to another service entrance between the wing and the MSB building. At street level is another, smaller entrance, with glass doors, accompanying the museum's gift shop to its south. The facade also overhangs this entrance, but to a lesser extent than its counterpart on the other facade. On the roof is a cafe, partially open, with views of the bridge, opera house, and harbour. Interior When used by the Maritime Services Board the interior made extensive use of scagliola and terrazzo to imitate marble flooring and walls, a common technique at the time. A war memorial and associated artwork were also included. These features remain in what was known as
