- Then to Now
The foundation of the Basilica-Cathedral is constructed of local sandstone from Signal Hill. Galway limestone and Leinster granite from Ireland were used for the interior walls and towers. Small amounts of sandstone from the Kelly's Island and Mistaken Point formations were quarried and used in the ambulatory walls.
Signal Hill sandstone was used in the restoration of the exterior walls. The impressive statuary throughout the Basilica was carved in Carrara Marble, quarried in Italy. Verona limestone, also from Italy, was used to construct parts of the high altar, while the side altars were adorned with Egyptian travertine.
