Église Saint-Jacques en Tarentaise de Tignes, Catholic church in Tignes 1800, France

The Église Saint-Jacques en Tarentaise stands in the Boisses area of Tignes, rebuilt in 1950–1952 after the original Romanesque church was submerged by the Chevril reservoir. Its stone walls and bell tower recall the old parish church, while inside the 18th-century gilded main altar and side altars to the Rosary and Saint Joseph were salvaged from the flooded building.

The building was constructed between 1950 and 1952 as a replica of the original Romanesque structure now submerged beneath Lake Chevril's waters. Reconstruction became necessary because valley flooding submerged the original site.

The church houses furnishings from the original building, including an 18th-century main altar and altars dedicated to the Rosary and Saint Joseph. These objects show how the community preserved its religious identity by saving pieces from its earlier church.

The church welcomes visitors mainly during the summer season with limited opening hours, so checking access times in advance is recommended. The location in Tignes is easily reached by public transport and roads, especially during summer months.

The church is dedicated to Saint James of Tarentaise, not of Assyria: the name refers to Jacques, a bishop of the Tarentaise see later venerated as a saint. The rebuilt church at Les Boisses keeps this dedication from the submerged original, so the parish name still points to the valley's own bishop rather than to an Eastern figure.
