After the demolition of the older church due to the new tramway line, a search began for a new site on the same street.
On August 23, 1906, the foundation stone was laid; construction stopped for a time because of financial difficulties, then resumed, and the building was completed.
The church was consecrated and opened for worship on February 15, 1912.
In 1932, it was elevated to the status of a “basilica.”
In 1949, an electronic organ was acquired and installed in the church.
In 1967, Pope Paul VI officiated a liturgy here.
