Designed by S.G. Locati from 1895-1896 for Pietro Reininghaus from Graz, a beer brewer and importer, this building is a free interpretation of late 19th century Viennese architecture. The brief provided by the owner included a large public beerhouse on the ground floor, on the façade towards the piazza, with rooms on the mezzanine floor, and a café-theatre covered by a large canopy in iron and glass alongside the main building, which is still visible inside the offices of the Banca Popolare di Milano. On the outside, the façade consists of a stone basement mounted by three floors built in brick, and a contracted top floor which was added after the Second World War.
