Commanderie de Montiracle

The Commanderie de Montiracle is a 13th-century commandery standing on a hilltop in the center of a small plain, with defensive walls and characteristic architectural features from that period. The building shows both elements from its original Templar construction and later additions made in the middle of the 15th century.

The commandery was founded in 1276 by the Templars of Lyon and served as their outpost. After the Templars declined, it passed to the Hospitallers, who substantially rebuilt and expanded it between 1436 and 1439 under Guillaume de Lastic's direction.

The name Montiracle comes from Latin mons-oraculi, meaning mount of oracles, suggesting earlier Roman or Celtic druidic activity at the site. This place held religious and military importance for the surrounding communities for many centuries.

The site now houses Mineralogica, a private museum displaying over 1200 mineral and crystallography specimens for visitors to examine. Its hilltop location offers views of the surrounding landscape and requires some climbing to reach the main buildings.

The coat of arms of Guillaume de Lastic remains visible above the entrance door and on an interior fireplace, marking the 15th-century construction work. These heraldic stones are rare survivors that show this commander's personal involvement in reshaping the site.
