Commanderie Sainte-Catherine

Commanderie Sainte-Catherine is a former Knights Templar commandery in the hamlet of Mercey, part of the commune of Montbellet, in the Saône-et-Loire department of Burgundy-Franche-Comté, eastern France. The property, made up of a chapel and an adjoining residential building, ranks among the region's few surviving traces of the Templar order's presence before its suppression in the early 14th century.

When was the commandery built, and who founded it?

The Templars held the estate at Mercey by the 13th century, using it as a working base that combined agricultural income with religious life, a common pattern for Templar houses across rural Burgundy. The chapel, the oldest and best-preserved part of the complex, dates from the close of the 13th century.

What survives inside the chapel?

The chapel is roofed with ribbed cross-vaulting typical of Gothic building practice around 1300. Its walls carry medieval murals of saints and apostles, whose style echoes the drawings of Villard de Honnecourt, a contemporary French master builder whose surviving sketchbook is a key source on medieval construction techniques. A wooden floor inserted in the 19th century now divides the vaulted volume, altering the chapel's original single, open space.

What happened after the Templar order was dissolved?

When the Templars were suppressed in the early 1300s, their French properties were transferred to the Order of Saint John of Jerusalem, the Hospitallers. In 1313 the Mercey commandery was attached to the commandery of Chalon, and it remained under Hospitaller administration - later that of the Knights of Malta - until 1790, close to the end of the order's presence in France.

How did the property pass into private hands?

The French Revolution ended the estate's ecclesiastical ownership. On 9 August 1796 the residence, chapel, two barns, stables and a garden were sold as national property for 5,500 francs. The buyers converted the former commandery into an ordinary working farm, a role the buildings kept for generations afterward. The residential building itself, in its present form, dates from the 15th century, with further alterations carried out in the 19th century.

Is the commandery a protected historic monument?

Yes. The residential building was listed as a monument historique on 27 March 2001, while the chapel - prized for its rare medieval vaulting and murals - received the higher classé status on 13 February 2002, France's top tier of heritage protection.

Frequently asked questions

Was this a Templar or a Hospitaller commandery? Both, in sequence: the Templars founded it in the 13th century, and after the order's suppression in 1313 it passed to the Hospitallers of Saint John, later the Knights of Malta, who administered it until 1790.

What is the single most notable feature to see? The chapel's ribbed vaulting and its late-13th-century murals of saints and apostles, whose design recalls the drawings of Villard de Honnecourt.

Can visitors go inside? The site is privately owned and still used as a farm, so anyone hoping to visit should check with the owners or Montbellet's local tourist information beforehand rather than expect open access.

Why is it called "Sainte-Catherine"? The name comes from the chapel's dedication to Saint Catherine, a saint widely venerated by medieval military-religious orders.
