As you probably know, in the year 732, the armies of Charles Martel repelled the Arab advance around Poitiers. A troop of routed Saracens then barricaded themselves in the old parish church of St Sauveur and promised to surrender only in the event of divine intervention. However, in this month of May, after nights of prayers by the villagers, a cold snap hit the Poitiers countryside to the point of covering the grove with an astonishing layer of frost. The Saracens saw the sign of Allah in this unexpected event and decided to leave the village without giving battle.
This legend gave its name to the village and the church of the Holy Trinity became a place consecrated by the religious authorities of the region. The oldest parts of the building that stands today on the small village square date back to the 11th century, but the church had to undergo several restoration campaigns during the 19th century. It now appears to us as a fine example of a Romanesque church, simple, rustic and austere. Note the modern stained glass windows made in the 1990s by Louis-René Petit, an artist who also worked in Sénanque and St Benoît sur Loire. His compositions inspired by frost give the church an atmosphere in harmony with its legend.
