The vast Gothic interior of Église Saint-Quiriace in Provins, France, begun in 1160, towers above the medieval town that grew wealthy from its great fairs. Despite its incomplete construction, the church dominates the skyline and offers a strikingly large scale for such a small community. On August 5, 1429, Joan of Arc attended Mass here alongside King Charles VII, linking this sacred space to one of the most storied moments in French history.
