The former cathedral of Orange sits two blocks from the Place de la République. Built in the 12th century in a sober Provençal Romanesque style, it lost its cathedral status when the diocese was suppressed during the Revolution. The west facade was damaged in the Wars of Religion in the 16th century, when the city was held by Protestant princes of Orange — what you see today is a 17th-century reconstruction with surviving Romanesque elements.
The interior is plain and quiet, with a single barrel-vaulted nave and a few baroque side altars. Note the worn Romanesque carving around the south portal. The cathedral is rarely busy — most visitors heading for Provence skip past Orange for Avignon — so it makes a peaceful pause between the two Roman monuments.
