Cavaillon Cathedral, Former cathedral in Cavaillon, France

Cavaillon Cathedral is a former Roman Catholic cathedral in Cavaillon, Vaucluse, built in the Romanesque style between the 11th and 13th centuries. Its single five-bay nave has a pointed barrel vault and is flanked by flat buttresses, with nine side chapels set between them. The octagonal bell tower rises above a dome on squinches over the choir, and the nave is topped by an entablature of architrave, frieze and cornice.

The church was built between the 11th and 13th centuries as the seat of the Bishop of Cavaillon, a role it held until 1801 when the diocese was merged into that of Avignon. Since then it has served as a parish church for the town.

The double dedication to the Virgin Mary and Saint Veran dates from 1228, when part of Veran's body was moved into the church; he is the patron saint of shepherds. The other part was transferred on 3 July 1321 by Bishop Pons de Lagnes, and Petrarch signed the record of that ceremony.

The building is an active parish church, so visiting outside of service times makes it easier to look around the interior without interruption. The cloister is accessible from the nave and can be explored without a long walk.

The octagonal bell tower rises above a dome on squinches over the choir bay, its arched openings fitted with abat-sons and framed by columns at the angles. A small spiral staircase serves it. In 1496-1497 the town built a separate campanile to carry a clock, which the art historian Jacques Thirion called lanky and mean beside the canons' old tower.
