Basilique Notre-Dame de la Trinité

The Basilique Notre-Dame de la Trinité is a Roman Catholic pilgrimage church in Blois, built from 1932 in the style of sacred modernism — an architectural language that deliberately broke from the historicist forms of the 19th century. Classified as a historic monument in France, it represents the interwar period's experiments with simplified geometry and reinforced concrete in ecclesiastical building. Dedicated to the mystery of the Holy Trinity, it continues to function as a pilgrimage site in the Loir-et-Cher département. Visitors find a contemplative space largely off the main tourist circuit centered on the nearby Château de Blois.
