The Basilica of Saints Peter and Paul (French: Basilique Saint-Pierre et Saint-Paul) in Lewiston, Maine, also known as Ss.

In the mid-nineteenth century, Lewiston had an influx of Roman Catholic French Canadians who came to work in the local textile mills.

Because of the large number of French-speaking parishioners, the masses were moved to the nave of Saint John's on July 2, 1870.

In 1902, the parish was split to create the Saint Louis church, across the river, in Auburn.

Finally, in 1933, the Diocese of Portland allowed the parish to build the top part of the church.

[3] It was reported in the Portland Press Herald that an influx of French-speaking Roman Catholic immigrants from central Africa have been a driving force in supporting the French-language mass.
