The Church of Il Gesù, or Church of the Holy Name of Jesus, is the main temple of the Jesuit order in Rome. Innovative and original for its time, it was one of the first announcements of a new style in construction - Baroque. It is worth noting the Baciccia illusionist fresco "Jesus Triumph" located on the church's vault. In one of the chapels the founder of the Jesuit order is buried - Saint Ignatius of Loyola.
The church plan and the body design were developed in 1568 by the Italian architect Giacomo Barozzi da Vignola, one of the most outstanding students of Michelangelo. The façade was erected in the years 1573–1584 according to the design of Giacomo della Porta. Her composition was quickly recognized as a model architectural solution.
Il Gesu is a prototype of many Baroque Jesuit churches located throughout Europe. His most famous Polish follower is the church of Saints Peter and Paul the Apostles in Krakow.
