Sainte-Croix-de-Tadoussac Mission Church, Historic wooden chapel in Tadoussac, Canada

Sainte-Croix-de-Tadoussac Mission Church is a wooden chapel in Tadoussac built with timber framing and covered in horizontal clapboard siding. The structure features a front-gable roof and small bell tower at its entrance, positioned along the river.

A first bark chapel was erected at Tadoussac in 1615; another followed in 1641, the year the first Jesuit settled there. In 1661 a stone chapel 18 metres long was built on land granted by governor Jean de Lauzon, but it burned in 1665. In 1747 Father Claude Coquart had the present chapel built; it was completed and first used for mass on 24 June 1750.

The chapel is known as the "chapelle des Indiens" (Chapel of the Indians). In summer 1668, Bishop François de Montmorency-Laval baptized 149 Indigenous people prepared by Father Henri Nouvel and celebrated mass in a bark chapel before 400 Montagnais. Religious objects and displays on missionary life in New France are shown inside.

The church is located on Rue du Bord-de-l'Eau in Tadoussac and is protected as a national historic site. Visitors should be prepared for changes in weather as it is a riverside location with limited shelter during tours.

The chapel's 1790 altar is signed by M. Émond, and its chandelier-confessional dates from the late 18th century. In summer 1668, Bishop François de Montmorency-Laval baptized 149 Indigenous people here, prepared by Father Henri Nouvel, and celebrated mass before 400 Montagnais in a bark chapel.
