The Basilica of Our Lady of the Rosary (French: Notre Dame du Rosaire de Lourdes) is a Roman Catholic church and minor basilica within the Sanctuary of Our Lady of Lourdes in France. Its main theme is a celebration and depiction of the Rosary.
The Rosary Basilica is the third of the churches to be completed on the site (after the Crypt and the Upper Basilica). It was designed by architect Leopold Hardy and completed in 1899. It was consecrated in 1901 and has a capacity of 1,500 worshippers. Its style is influenced by Byzantine architecture.
In 2006-7 the interior and exterior of the basilica were extensively renovated and the mosaics (many of which were deteriorating) were restored.
