This large stone with rounded shapes is over three metres high and is often referred to as a “menhir”, although no features corresponding to an authentic menhir has been identified (a menhir is a large upright standing stone erected by man between 3500 and 2000 BC). Different interpretations have been given about its origins: is it a mere remnant of one of the Combalou's many fallen rocks, upon which a cross was carved in medieval times to turn it into a territorial marker, a boundary stone for instance, between the Montclarat and the Tournemire communities? Or is it an ancient menhir that was Christianised (2 crosses deeply engraved next to each other) as so many other megaliths were?
