He was an architect who created many different works such as the Constable's Chateau, Régle générale d’architecture des cinq manières de colonnes, and tombs. He also created several chateaus. One of his patrons was named Catherine de Medicis. One of his many great works was the church os St. Accuel. It was created in the 16th-17th century.
