Late 1950s socialist realism meets post-war Soviet art at the NI HQ of the Transport & General Workers Union (TGWU). The striking façade features a huge mural depicting giant marching men, an airplane and a ship - each representing Belfast's engineering heyday. The TGWU plans to vacate this listed building so don't be surprised if it eventually becomes yet another achingly fashionable designer bar. Meanwhile, it could do with a good clean.
