The history of Montricoux was particularly marked by the founding of the Knights Templar by Vaour commandery in the thirteenth century. In Montricoux, the Templars first built the tower and a castle, which they joined with the monastery. The dungeon was much higher than it is now, and included a low vaulted room with no opening behind the narrow loopholes on the south façade. Above, there were three floors and a crenellated platform. On the corners stood four turrets corbelled, embattled also, in the northwest spiral staircase that served the various steps, and could be accessed through a door in the castle, in a wooded gallery in the lower room on the first floor level. The construction of the tower was completed in 1287. The castle and its outbuildings were destroyed in the sixteenth century during the Wars of Religion, from a fire caused by an attack of CalvinistMontauban, only the tower was spared. A symbol of lordly authority, the tower was unfortunately mutilated during the French Revolution by the population. It stayed long in a state of ruin, before its walls were leveled and a roof is put in place. The Templars likely constructed the oldest part of the present church, which corresponds to the entrance porch and hasRomanesque architecture of the twelfth century. The various pieces of cartulary from Templars and Vaour related to Montricoux, show that five churches existed in the twelfth century on the current extent of the municipality. Besides the church of Saint-Pierre the Chapel of Saint-Félix became the church of St. Lawrence Mairessi, and then Maynet. The church of Saint-Genies disappeared since the revolution after annexation of territory to the common Montricoux, the church of Saint-Benoît de Castres to be constructed prior to 1000 AD, now disused is private. The cult was celebrated until the Revolution took place and a pilgrimage every year to implore the healing of the sick children, it continued until the nineteenth century. The fifth church was located at Bourbou and was likely dedicated to Saint Madeleine Sophie Barat. It remains today a section of wall whose apparatus sitting at some fern leaves characterizes the Merovingian period. The place where it is located was named Madeleine in the eleventh century and the late nineteenth century, just as St. Géniès in a field should be the parish cemetery, plowing were often discover human remains.
