The devastating 1667 Dubrovnik earthquake ruined the fledgling college and killed many of its students. The current complex was then built on plans by Jesuit architect and artist Andrea Pozzo (1642–1709), then renowned for his prior work at the Roman church of Saint Ignatius. The church's construction was started in 1699 and completed in 1725. A sculpted plaque dated 1481 showing angels holding a medieval YHS christogram above a Latin inscription, was placed prominently at the base of the staircase leading to the College's entrance. It almost certainly comes from a religious building destroyed in the 1667 earthquake and viewed as a precursor of Jesuit iconography, possibly the church of Saint Lucia that used to stand on the location of the Jesuit steps.
