Diocesan museum of sacred art (Arezzo)

The Diocesan Museum of Sacred Art (MuDAS), Italian Museo diocesano di arte sacra, is a museum of religious art in Arezzo, Italy. Founded in 1963, it opened regularly to the public only in 1985 and was originally housed above the sacristy of the Cathedral of San Donato. In 2011 it moved to the first floor of the bishop's residence, the Palazzo Vescovile. The museum holds works from the 12th to the 19th centuries drawn from the cathedral and other churches across the Diocese of Arezzo-Cortona-Sansepolcro, making it a significant repository of the region's religious and artistic heritage. Its collections include notable works by Giorgio Vasari and the Pace di Siena, and it serves as a center for teaching, temporary exhibitions, and restoration.

The museum was established in 1963, though it did not open to the public on a regular basis until 1985. For its first decades it occupied several rooms above the sacristy of Arezzo's Cathedral of San Donato. A major relocation occurred in 2011, when the collection was moved to the first floor of the Palazzo Vescovile, the bishop's palace. This move significantly expanded the museum's facilities and public profile. The museum is now integrated into the cultural programming of the Diocese of Arezzo-Cortona-Sansepolcro and maintains active roles in conservation, education, and exhibition-making.

The museum's holdings span six centuries of sacred art and liturgical practice, from the 12th to the 19th centuries. The collection is organized across five rooms in an itinerary that addresses the history, art, and devotional traditions of the diocese. Materials encompass painting, sculpture, illuminated manuscripts, liturgical vestments, goldsmith work, and metalwork. The geographic scope extends beyond the cathedral itself to include works from churches throughout the diocesan territory, reflecting the broad religious and cultural landscape of the Arezzo region. The collection is particularly strong in medieval and Renaissance periods, with significant groupings of works by local and regional masters.

The first room contains the oldest objects, including a 12th-13th century painted wood crucifix, 13th-century bronze thuribles from Arezzo workshops, and the Pace di Siena, an early 15th-century Franco-Flemish gold, enamel, and jewelwork piece depicting Christ on the cross with angels and the Virgin of Sorrows, housed in an 1815 reliquary by Giuseppe Spagna. Also present are Andrea di Nerio's Annunciation (1375-1400), detached frescoes by Spinello Aretino from 1377 and 1380-1385, a polyptych attributed to Stefano di Antonio di Vanni (1430-1440), and a terracotta tabernacle attributed to Bernardo Rossellino (1434).

The second room holds a 14th-15th century rock crystal and gilt copper processional cross of the Venetian school, a mid-15th century painted terracotta bust of San Donato attributed to Luca della Robbia, a late 15th-century detached fresco of St. Jerome by Bartolomeo della Gatta, a predella from the workshop of Luca Signorelli (1518-1519), and a late 17th-century southern Italian episcopal mitre embroidered with gold thread and coral.

The third room is devoted almost entirely to Giorgio Vasari, featuring his Preaching of John the Baptist and Baptism of Christ, both from 1548, and his Madonna of Mercy from 1560-1570. This room also contains Christ at the house of Martha and Mary (1575) by Santi di Tito.

The fourth and fifth rooms present 17th- to 19th-century works, including purple and gold liturgical vestments and three oil paintings by Pietro Benvenuti from the late 18th to early 19th centuries.

The museum currently occupies the first floor of the Palazzo Vescovile, the bishop's residence in Arezzo, to which it relocated in 2011. This move from its former location above the cathedral sacristy provided expanded and more suitable exhibition spaces for the collection. The Palazzo Vescovile itself is a significant historic building, and visits to the museum can include the piano nobile with its frescoed rooms by the Papacello, a picture gallery, and the bishop's bedroom, indicating that the museum functions within a larger palatial complex of architectural and historical interest.

The Diocesan Museum of Sacred Art is located in Arezzo, Italy, within the Palazzo Vescovile. It is owned and operated by the Diocese of Arezzo-Cortona-Sansepolcro. The museum is accessible to visitors with disabilities and provides facilities for teaching activities. In addition to its permanent collection, it hosts temporary exhibitions and serves as a center for restoration work. The museum maintains an official website through the diocesan portal, and its holdings are registered with the national ecclesiastical cultural heritage offices of the Italian Bishops' Conference.
