Église Saint-Theudère de Saint-Chef, Romanesque church in Saint-Chef, France.

Église Saint-Theudère is a Romanesque church built of light tan stone under a dark brown tiled roof, with a square tower topped by a pyramidal roof on the left. Its three-aisled nave of seven bays rests on round-arched arcades carried by octagonal pillars, and the vaulting was raised in the 15th century. A Gothic portal replaced the Romanesque west portal in the 15th century.

Theudarius of Vienne, a disciple of Caesarius of Arles, founded a Benedictine monastery here in the 6th century and was buried in it. After Norman raids destroyed it, Archbishop Barnoin of Vienne had it rebuilt with monks from Montier-en-Der. The church was completed in the 12th century, when the abbey held authority over a dozen priories and about 80 parish churches. In 1320 the pope subjected it to the Archbishop of Vienne, and in 1536 it became a college of canons, suppressed in 1774.

The frescoes in the Chapel of Angels depict scenes from the Revelation of Saint John with bright colors that have survived to today. These images were meant for believers who could not read and tell religious stories on the walls.

Access to the upper chapel with its frescoes is available and allows time to explore all the details. It is advisable to wear comfortable shoes and bring adequate lighting to fully view the wall paintings.

The Chapel of the Angels, reached only by a steep spiral staircase, kept its 12th-century Apocalypse frescoes intact because canons stored their archives there in the 16th century; the cupboards hid the paintings until they were restored between 1959 and 1961.
