Architectural plans for a canal spanning from Toulouse to Carcassonne were submitted to Francis I in 1539 by Nicolas Bachelier and Arnaud Casanove. These technical documents, formulated by the two men in their capacity as expert levelers, proposed methods for river navigation that were subsequently approved by the monarch but ultimately deemed impossible to implement.
Early Life and Professional Scope
Born in Arras in 1487, Bachelier lived until 1556, passing away at the age of 69 in Toulouse. He established a professional career within France that encompassed roles as a surveyor, architect, and sculptor. During this period, the architectural profession shifted toward a model where individuals asserted authority through formal drawings and personal signature styles rather than solely through on-site craftsmanship.

Take the IQ test →Renaissance Contributions to Toulouse
Bachelier is noted for his contributions to the construction of various hôtels particuliers during the Renaissance. His portfolio includes the Hôtel de Bagis, which dates to 1538, and the Hôtel de Guillaume de Bernuy, constructed between 1540 and 1544. His work further includes the classical façades of the hôtel d'Assézat, completed between 1555 and 1556. Beyond these residences, his output is identified in religious sculptures, medallions for the Hôtel Jean de Pins and Hôtel Thomas de Montval, and potentially the telamons located at the Hôtel du Vieux-Raisin.
Infrastructure and Engineering Proposals
In addition to his building designs, Bachelier engaged in hydraulic engineering proposals. His 1539 submission to Francis I contemplated a route connecting the Garonne River toward Bordeaux, involving a canal parallel to the river flow. While these initial schemes were reconsidered by Henri IV in 1598, the project remained dormant for decades until Pierre Paul Riquet initiated the Canal du Midi in 1662. The château de Caumont also remains an attribute linked to his career.
