The Church of the Gesù is the mother church of the Society of Jesus (Jesuits). It was built on the same spot as the previous church Santa Maria della Strada, where St Ignatius of Loyola had once prayed before an image of the Holy Virgin. This image, now adorned with gems, can be seen in the church in the chapel of St Ignatius on the right side of the altar. The façade of this church is “the first truly baroque façade”, introducing the baroque style into architecture, but St. Ignatius Chapel, located on the left side of the transept, is the church’s masterpiece. It houses the saint’s tomb and the restored macchina barocca or conversion machine of Andrea Pozzo who also painted the allegory of the Apotheosis of St. Ignatius in breathtaking perspective.
