This museum will take you on a fabulous journey through four centuries of Siena painting, from the first Primitives, much marked by the priestly manner of the Byzantine style by Sodoma, grand master of Siena painting from the 16C and, even if the two grand masters of Siena, Duccio and Simone Martini, are poorly represented there, this visit is enchanting. Siena painting is characterised here not just by the evolution of style but also by the ever-present gracefulness.
