The Royal Monastery of Brou is a religious complex located at Bourg-en-Bresse in the Ain département, central France. It is composed of monastic buildings and a church, which were built at the beginning of the 16th century by Margaret of Austria, daughter of the Holy Roman Emperor Maximilian I and Governor of the Habsburg Netherlands. The complex was designed as a dynastic burial place in the tradition of the Burgundian Champmol and Cîteaux Abbey, and the French Saint-Denis. The church is known as the Église Saint-Nicolas-de-Tolentin de Brou in French.
