The church was built on top of an area where multiple graves deriving from the times of the Punics, Phoenicians and the Romans were excavated.

The catacomb was changed into a medieval Christian crypt and a gothic doorway was built.

The ceiling might also have been supported with pointed arches, typical architecture for Maltese medieval churches.

Dusina's visit in 1575 reports that the church has one altar with a painting covered by a yellow drape.

In 1444, Archbishop Paul Alphéran de Bussan mentions that the church had numerous art works depicting the Virgin Mary and other saints.

Ex votos were also hung near the painting of the Virgin Mary, indicating that the church served as a devotion spot for many.

In 1986 the statue of the Redeemer was removed from the premises of the church and was restored and reinstalled in the grounds of the Major Seminary, near by.
