Pinacoteca Nazionale (Siena)

The Pinacoteca Nazionale is a national museum in Siena, Tuscany, Italy. Inaugurated in 1932, it houses especially late medieval and Renaissance paintings from Italian artists. It is housed in the Brigidi and Buonsignori palaces in the city's center: the former, built in the 14th century, it is traditionally identified as the Pannocchieschi family's residence. The Palazzo Bichi-Buonsignori, built in the 15th century, was until recently thought to have a 19th-century neo-medieval façade based on the city's Palazzo Pubblico; however, restoration in 2022 revealed that it is mostly original.

The gallery has one of the largest collections of Sienese paintings with gold backgrounds from the 14th and 15th centuries.

Works in the gallery include:
 * Duccio di Buoninsegna's Polyptych N. 28 and Madonna of the Franciscans
 * Guido da Siena's St. Peter Enthroned
 * Simone Martini's Blessed Agostino Novello and His Miracles (c. 1330)
