3 Best Sights in Aix-en-Provence, Provence

Many eras of architectural history are clearly delineated and preserved here. The cathedral has a double nave—Romanesque and Gothic side by side—and a Merovingian (5th-century) baptistery, its colonnade mostly recovered from Roman temples built to honor pagan deities. The deep bath on the floor is a remnant of the total-immersion baptisms that used to occur here, marking the forsaking of one's old life (going down into the water) for a new life in Christ (rising up from the water). Shutters hide the ornate 16th-century carvings on the portals, opened by a guide on request. The guide can also lead you into the tranquil Romanesque cloister next door, with carved pillars and slender columns.

The extraordinary 15th-century Triptyque du Buisson Ardent (Mary and the Burning Bush) was painted by Nicolas Froment in the heat of inspiration following his travels in Italy and Flanders, and depicts the generous art patrons King René and Queen Jeanne kneeling on either side of the Virgin, who is poised above a burning bush. To avoid light damage, it's rarely opened for viewing; check with the tourist office beforehand.

Though the facade now bears 19th-century touches, this small 17th-century church still contains the center panel of the fine 15th-century Annunciation Triptych, attributed to the father of Jan Van Eyck, the greatest painter of the Early Netherlandish school. Some say the massive painting on the left side of the transept is a Rubens. The church is used regularly for classical concerts.

This 12th-century church served as a chapel of the Knights of Malta, a medieval order of friars devoted to hospital care. The church was Aix's first attempt at the Gothic style, and it was here that the counts of Provence were buried throughout the 18th century; their tombs (in the upper left) were attacked during the revolution and have been only partially repaired.
