the history of the castle of macconago dates back to 1030 when a square defensive structure was first erected, completed in 1040 with the construction of a series of watchtowers. the structure was entrusted in castellania to the pusterla family (whose coats of arms can still be admired today at the two main entrances on the front and back), which however fell out of favor with the visconti, who definitively requisitioned the castle, later entrusted to the vimercati family, then passing to the calchi family, the marliani, the ferrario, the tarlaini, the greppi and the gavanas, current owners of the structure.
