Église Sainte-Anne de Saint-Nazaire, Catholic church building in Saint-Nazaire, France.

Église Sainte-Anne de Saint-Nazaire is a post-war church built of concrete. A tall, narrow dark brown rectangular bell tower with a slightly flared top stands beside a lower rectangular hall; its front face carries a vertical strip of small square openings. The hall's upper facade is light brown textured concrete pierced by rows of small round recessed holes, above a wide undercroft on horizontal beams, with red vertical siding and a tall rectangular window at the far right.

The foundation stone was laid in 1956 and the church opened to the public in 1959, replacing the demolished Matte chapel. It was built while Saint-Nazaire was rebuilding after wartime destruction. The church has been listed as a monument historique since 29 May 2019.

The church is named after Saint Anne and reflects the faith of the post-war community. The interior with its artworks created by local and international artists shows how worshippers gather here and use the space as a place of prayer.

The church is located on Boulevard Jean Mermoz and is easily accessible in the center of Saint-Nazaire. Visitors should know that the interior is best viewed during daylight when natural light flows through the windows.

The building completely abandons traditional side aisles and transepts, instead creating a single, flowing space. Biblical symbolism sits atop the bell tower and is visible from across the city.
