The Basilica of Notre-Dame, Marienthal, is a Catholic pilgrimage church dedicated to Mary, mother of Jesus. Located in Marienthal, in the Bas-Rhin department of France, it is administratively situated in the town of Haguenau.
Pope Pius IX crowned the dolorous Marian image enshrined within in 1859. Pope Leo XIII elevated the status of the shrine to Minor basilica in 1892.
The first sanctuary at this site was built around 1250 by the knight Albert of Haguenau, who had had a religious epiphany some ten years prior and had gathered a small community of faithful around him. This first sanctuary, called "Mary in the Valley", venerated a statue of the Madonna and Child which is not preserved today.
