The palace was built in 1565/1570 by Bartolomeo brother of the Nicolosio L. in Strada Nuova. It was included in the rolls from 1588 to 1664 and subsequently passing through the female line to the Rostan Reggio family. It was finally bought by the Raggio family in 1892. It stands in the middle of a residential area which, with its wide-open spaces, seem suburban rather than central. It stood outside the 12th,centuty walls but was inside the old walls (1320,1536) and its original disposition seems to fit it snugly into the depression of Vallechiara. This is how it appears in Rubens’ view, elongatted and harmoniously arranged by pictorial quadratura into axes (1622 ed.; Palazzo I).
