Installed at the top of a hill, on the territory of the commune of Lournand, in Saône-et-Loire, the castle of Lourdon was originally the property of the abbots of Cluny. Built in the 9th century, it quickly aroused the envy of many lords, which earned it the protection of the kings of France Louis VII and Philippe Auguste.
Important refuge for monks in the 14th century, it was subsequently ravaged by the troops of Louis XI, then Charles the Bold before undergoing major restoration campaigns at the end of the 15th century. Rebuilt at the end of the 16th century by Claude de Guise, who then put it back in a state of defense, the Château de Lourdon was subsequently definitively destroyed in the 17th century by blasting at the request of the States of Mâconnais.
Sold as a national asset during the French Revolution, the site today in ruins is accessible to the public in the summer season and benefits from significant development thanks to the Castrum Lordo association.
