Carla-Bayle is a commune in the Ariège department in southwestern France. It was the birthplace of Pierre Bayle (1647–1706), a Protestant philosopher and writer known for his works on religious toleration and his early encyclopedia.
Originally named Carla-le-Comte, the commune became a center of Protestant activity in the 16th century before the government suppressed it. Protestant philosopher and writer Pierre Bayle was born there, and was taught in his early years by his father, a Protestant minister. He briefly converted to Catholicism, before reverting to the Protestant Reform faith. His rejection of Catholicism led to his need to leave France. Later the government oppressed Protestants, who remained the majority in Carla. A Protestant strong point it was besieged by the royal army and its walls and chateau demolished.
During the revolution the commune was renamed Carla le peuple. After the monarchy was restored it was renamed Carla-Bayle in honor of Pierre Bayle. There is a museum devoted to Bayle and is home to many galleries and a number of artists.
