Museo dell'Opera Metropolitana del Duomo

The Museo dell'Opera del Duomo is an art museum in Siena, in Tuscany in central Italy. It houses works of art and architectural fragments that were formerly in, or a part of, the Duomo of Siena. These include a number of Italian Gothic sculptures by Giovanni Pisano and his school from the façade of the cathedral; the Maestà of Duccio di Boninsegna, which was the cathedral's altarpiece in the crossing beneath the dome from about 1311 until 1505 or 1506.
