The foundations were completed by late winter 1909, and on July 2, 1912, during the Feast of the Visitation, the initial portion of the church was inaugurated in a solemn ceremony presided over by Bishop Turinaz.

The main portal was finished on October 1, 1925, and the spire was inaugurated on September 22, 1929, accompanied by a "Te Deum" celebration.

Additional works, including the spire's sculptural restoration in 1931 and the narthex in 1933, marked the final stages of construction.

Designed by Jules Criqui, the basilica combines elements of Romanesque and Gothic styles to meet the respective preferences of Bishop Turinaz and Abbé Loevenbruck.

The tower houses eight bells, including "Jeanne d'Arc" (the bourdon) and others named for Catholic saints such as Thérèse and Bernadette.
