The Rialto, Winfield and Olderfleet building group, in Collins Street, Melbourne, is a group of five historic buildings all built within a few years of each other in 1888-1891. They are all a similar height, width and level of detail, making up one of the most notable historic streetscapes in Melbourne, and a particularly notable Victorian streetscape in the international context.[1] All the buildings were subject to preservation battles in the 1970s and early 1980s, ultimately saving the front portions of four of them, and the whole of one of them, the Rialto.
