Chapelle Saint-Yves de Vannes, Baroque chapel in Vannes, France

Chapelle Saint-Yves de Vannes is a baroque chapel in the French city of Vannes featuring white stone walls built on a granite foundation. The building displays a tall facade with triangular pediment and the IHS monogram, while its interior preserves an altarpiece designed by Jean Boffrand in 1684 with black marble columns and religious artwork.

A first chapel and college were built in 1577 and entrusted to the Jesuits in 1629–1630. The chapel was rebuilt from 1661 to 1685 on plans by Jesuit brother Charles Turmel, funded by Catherine de Francheville; the first stone was laid on 27 September 1661 by Guillaume Bigarré, and Jean Caillot finished the facade in 1678. It was listed as a monument historique on 25 January 1929 and reopened on 22 January 2022 after restoration.

The chapel is named after Saint Yves, patron saint of lawyers, reflecting the Jesuit connection to the building and its community. The restored interior decorations with black marble columns and religious scenes continue to express the spiritual focus of those who gathered here to pray.

The chapel stands on the north side of Place Maurice-Marchais, next to the former Jesuit college Jules-Simon and close to the town hall. It was closed to the public for safety reasons in 1991, restored between 2020 and 2021, and inaugurated on 22 January 2022. It is not open for worship services.

A crypt lies beneath the choir area where coffins were once stored before being removed during the French Revolution, something not immediately visible to visitors today. This hidden history shows how the building's purpose and use changed dramatically over the centuries.
