In the floor to the right of the high altar is the simple tomb-slab covering the entrance to the crypt of the family of Gianlorenzo Bernini. It displays the family's heraldry, and the epitaph, which translates to: "Here the noble family Bernini waits for the Resurrection". The architect himself has been given a short Latin epitaph of his own which is carved into the step adjoining: "Gian Lorenzo Bernini, the glory of the arts and of the city, here rests humbly".
