The Church of Jesus is in Piazza della Collegiata in Castiglion Fiorentino, leaning against the ancient Parish Church of San Giuliano and was built by the Congregation of the Blessed Sacrament between 1527 and 1545. The facade consists mainly of a portico with five round-arched arcades with cross vaults, supported by six stone pillars.
The church is built on three floors: the first incorporates the ancient town gate of San Giuliano, the middle one houses an oratory with cross vaults and fresco decorations, while at the level of the square the oratory of the Sacrament, or Jesus, was placed. This was so named because a Wooden Crucifix of the school of Baccio da Montelupo from the early 16th century was placed in the high altar.
The interior is presented as a single hall dominated by an extraordinary wooden coffered ceiling with Passion motifs, executed in 1615 by Niccolò Becci in collaboration with Sallustio Lombardi.
In addition to the aforementioned crucifix of the 15th-century, there is a 17th-century Dead Christ by a Roman sculptor. On the right altar is the Resurrection (1599) by Francesco Vanni, while opposite is a Last Supper (1586) by Francesco Morandini. The other four canvases, depicting episodes from the Passion of Christ, are the work of Mazzuoli, an artist from Siena.
