The Duomo Vecchio or Old Cathedral (also called "La Rotonda" because of its round layout) is a Roman Catholic church in Brescia, Italy; the rustic circular Romanesque co-cathedral stands next to the Duomo Nuovo (New Cathedral) of Brescia. It is officially known as the Winter Co-Cathedral of Santa Maria Assunta, while the adjacent main cathedral is known as the Summer Cathedral.
It is one of the most important examples of Romanesque round church in Italy.
While some claims for an earlier construction exist, the earliest documents state the cathedral was built in the 11th century on the site of a prior church with a basilica layout. It has a circular shape that became rare after the Council of Trent.
In the 19th century, many additions to the original medieval building were removed. The entrance portal is one later addition remaining. It contains the medieval Crypt of San Filastrio, in honor of the beatified Brescian bishop.
Near the entrance, rests the sarcophagus of Bishop Berardo Maggi (1308) made of red marble. The Duomo Vecchio contains l'Assunta(1526) and St. Luke, St. Mark and the sleeping Elijah (1533 - 34) by Moretto da Brescia. It contains a Gathering Manna by Gerolamo Romanino and a Translation of the Bodies of Saints by Francesco Maffei.
