Originally built in 1723 for Johannes Redolfi, it was purchased around 1850 by Baron Giovanni of Castelmur who renovated and expanded the building. The striking facade in the Lombardian/Venetian gothic style is part of this expansion, carried out by various Milanese craftsmen such as engineer and architect Giovanni Crassi-Marliani, stonemason Giovanni Pedrazzini and painter Gaspare Tirinanzi.
