The façade of the basilica, completed in 1886, is built in exposed brick with architectural elements in travertine and rises on a high double ramp staircase that leads to a large five-arched portico. On the façade above the portico is a row of five arched windows with projecting molded archivolts resting on corbels, and above these is a row of six tondi containing relief sculptures of the symbols of the Evangelists, the Lamb of God and the Sacred Heart.
