Archives record that in about 700, there was a basilica dedicated to Our Lady on the site of the current church. It was destroyed in 1287 and only the bell tower, known as the Green Tower, survived. The second church was consecrated in 1347. A vaulted choir, a sacristy with its vaulted intersecting ribs, a 3-nave structure, the bell tower and a sculpted door remain from this period. The chapel and the south sacristy were added in the 19th century.
