The Basilica of the Assumption of Our Lady (Czech: Bazilika Nanebevzetí Panny Marie) in Old Brno Abbey is a high Gothic, monumental convent temple.

It was built on the site of an ancient sanctuary from the late 10th century in a short time in the years 1323 to 1334 at the instigation of Queen Elizabeth Richeza.

In 1323 the double queen - royal widow Elizabeth Richeza founded a Cistercian convent (in Latin) called Aulae Sanctae Mariae beside to the oldest pre romanesque parisch church of Oure Lady in Old Brno.

The Augustinians also had a glorious "silver altar"[4] in baldachin form made in Augsburg and erected when the icon of the Black Madonna was crowned in 1736.

At the Feast of the Assumption of Our Lady a pilgrimage is held every year on August 15 in the basilica to worship her as the Protector of the city of Brno.
