The church was severely damaged by an earthquake in 1688 and another in 1702, which collapsed the original dome and some later medieval additions. Cardinal Orsini, the future Pope Benedict XIII, had the church rebuilt in Baroque style. The restoration work, started in 1705, transformed the plan from a stellar to a circular one, added two side chapels, and changed the appearance of the apse, of the façade and of the pillars. Further, the frescoes which decorated the interior were mostly destroyed: today only a few fragments, depicting the "Stories of Christ and Mary", remain.
