The Jesuits arrived in Palermo in 1549, and by the late 16th century began building a church adjacent to their mother house using a design by the Jesuit architect Giovanni Tristano. The original design called for a single nave with large transepts and several side chapels, but it was changed by the early 17th century, to a more grandiose layout typical of Jesuit architecture. Natale Masuccio removed the chapels' dividing walls to add two side naves to the central one. The church was consecrated in 1636. The interior decoration included marble bas-reliefs on the tribuna depicting the Adoration of the Shepherds and Adoration of the Magi, by Gioacchino Vitagliano, after designs attributed to Giacomo Serpotta - both reliefs survive. A fresco of the Adoration of the Magi was also added to the walls of the second side-chapel to the right by Antonino Grano in the 1720s. The church also contains a relief of the Glory of St Luke by Ignazio Marabitti. In 1892, cavaliere Salvatore Di Pietro, former rector of the Casa Professa, philanthropist, prefect of studies at the seminary, and member of the Theological College, of the Academy of sciences, letters and arts and of the Accademia di storia patria, convinced in 1888 the minister of public education, Paolo Boselli, to decree the church a national monument. In 1943, during the Second World War, a bomb collapsed the church's dome, destroying most of the surrounding walls and most of the wall paintings in the chancel and transepts. These frescoes were replaced during two years' restoration work, after which the church reopened on 24 February 2009 with a solemn mass presided over by Paolo Romeo, archbishop of Palermo, and attended by several Jesuits and civil and military officials.
Architecture
The facade is divided into two sections by a cornice. In the lower part there are three portals, above are niches with statues of St Ignatius of Loyola, a Madonna with Child and Francis Xavier. The upper section is divided by pilasters and framed on both sides with corbels and statues of saints. The facade is surmounted by a curved-segmented gable and the Jesuit emblem. Masucci originally planned belfries, but these were not completed, and the current 18th-century campanile was built on the adjacent Palazzo Marchesi. Behind the church, the Jesuit chapter houses the town library. The layout is in the shape of a Latin cross. The nave is 72.10 m long, 42.65 m wide and 70 m high and is decorated with polychrome marbles, stucco and frescoes. In particular, the marble reliefs with their figural and ornamental motifs on the pillars and the marble mosaics are unique. The rebuilt structure has a double dome and stained glass windows.
