The Museo Statale d'Arte Medievale e Moderna gives Arezzo's art story more room than the quick church circuit allows. Housed in Palazzo Bruni-Ciocchi, it gathers medieval and Renaissance painting, sculpture, ceramics, coins, arms, and decorative arts in rooms that still feel tied to the city's old noble families.
It is a strong second-tier stop after the Piero della Francesca frescoes and Piazza Grande. The collection rewards slow looking rather than box-ticking: look for the way local artists, Sienese influence, and broader Tuscan styles overlap. It is also a useful rainy-day choice, since Arezzo's best pleasures are otherwise spread through steep streets and church interiors.
