At the foot of the 328 feet (100 m) high rock of Lapopie sits the church and its bell tower. Founded in the 12th century, it is identifiable thanks to its square shape. It is also renowned for its staircase turret overlooking the village and the valley from the cliff’s edge. The church was rebuilt during the 15th century. The only remains of the Roman period are the apse and remnants of frescoes. Inside is an altar dedicated to Saint-Cirq, the youngest martyr in Christian history, who gave his name to the locality.
