The story
Founded by Elizabeth Richeza of Poland in 1323.1
The Augustinians arrived in Brno in 1346, and John Henry of Luxemburg (Jan Jindřich Lucemburský), Margrave of Moravia, began the construction of their original cloister in 1352. These premises are located on Moravian Square. In 1650s, a musical foundation for the monastery was established, with paid musical scholars. This was the early beginning of a long and significant musical tradition at the Brno monastery. In 1780s, the Emperor Joseph II forced the friars to move out because he liked their well-located and representative buildings. These were given to the governor office and the church was turned to standard parish church. The friars moved to suburban Staré Brno where they took over the abolished Cistercian convent and church.
Czech composer Pavel Křížkovský also took monastic vows at Brno, teaching liturgical music from 1848 until 1872, and from 1865 he formed an ongoing musical collaboration with the young (lay) composer Leoš Janáček who had come from his home in Hukvaldy and begun as a choirboy at the monastery.
