AURELIUS MONASTERY IN THE ROMANESQUE STYLE
There was probably a monastery in Hirsau as early as 830, likely dedicated to St. Aurelius. Instigated by his uncle, Pope Leo IX, Count Adelbert II von Calw had the dilapidated complex rebuilt in the Romanesque style in the mid-11th century. It consisted of the Church of St. Aurelius, parts of which are still preserved today, and two adjacent chapels to the north as well as a small conclave to the south. The entire monastery was enclosed by a wall and was accessible through three gates.
