Éauze Cathedral, Gothic Catholic cathedral in Eauze, France

Eauze Cathedral is a late Gothic church built from 1467 to 1521, about 50 m long and 18 m wide, with a single nave over 21 m high and 13 side chapels. Its rough grey-brown stone walls, high buttresses and flamboyant window tracery are visible outside; inside, seven bays carry four-part ribbed vaults and a polygonal apse closes the choir.

The present church was built between 1467 and 1521 under prior Jean Marre, on the site of an earlier church. It was damaged in 1569 during the Wars of Religion. The Benedictine priory buildings were restored in 1732, and the church was restored between 1860 and 1878.

The church is dedicated to Saint Luperculus, whose relics were transferred here in the 11th century when the Benedictine monastery changed its dedication. A 5th-century stele found in 1880 during work on the Eauze railway station, now in the Musée de Saint-Germain-en-Laye, is the oldest evidence of his cult in Eauze.

The church stands in the centre of Eauze, on the Via Podiensis route to Santiago de Compostela, and is listed as a monument historique since 1945. Enter from the west front; the nave is 10.70 m wide and 21.65 m high, with 13 side chapels along the walls. The stone floor and rough masonry make the interior cool, so bring a layer even in summer.

The church is often called a cathedral, but the archdiocese of Eauze had already died out in the 9th century; in 1865 the archbishop of Auch gave the title back. The building itself was raised between 1467 and 1521 under prior Jean Marre.
