(b. ca. 1460, Rivalta, d. 1530, Parma)
Italian architect from Rivalta (near Torrechiara). Architecture in Parma was dominated by the personality of Zaccagni. He is credited with designing the church of Madonna della Steccata in Parma, although the modernity of its centralized plan has led some to suggest that it was actually Bramante's invention. As a way of explaining the presence of a building of such refinement in a city which was by all accounts peripheral, it has also been hypothesized that the Parmese architect may have been inspired by a major artist such as Leonardo. Zaccagni, with the assistance of his Gianfrancesco, worked at the Steccata until he and his son were dismissed in 1525.
Zaccagni was also responsible for the design of the Oratory of the Immaculate Conception, a centralized structure beside the church of San Francesco del Prato, as well as some minor works in Parma.
