The biggest Baroque project was the rebuilding of renaissance Dubrovnik after the catastrophic earthquake of 1667 when almost the entire city was destroyed. Many of its churches and public buildings were constructed from the ground up in the new Baroque style, for example the new cathedral, the Jesuit college with the church of St Ignatius, and the church of St Vlaho on the main square (1715) which shaped the southeastern section of the city. Pietro Passalaqua united the new baroque areas with his "Jesuit Stairway", (reminiscent of the famous "Spanish Steps" in Rome) which led to the "Ivan Gundulić Square" below.
