About

The analemmatic dial of the monastery of Brou is located on the parvis of the church of Saint-Nicolas-de-Tolentin of the Royal Monastery of Brou in Bourg-en-Bresse, France. Made in the early 16th century, it is often considered the first of its kind. The dial deteriorated in the 18th century, the astronomer Joseph Jérôme Lefrançois de Lalande then invested in its renovation.
