SS. Trinità al Monte Pincio

The church of the Santissima Trinità dei Monti, often called merely the Trinità dei Monti (French: La Trinité-des-Monts) is a Roman Catholic late Renaissance titular church in Rome, central Italy. It is best known for its commanding position above the Spanish Steps which lead down to the Piazza di Spagna. The church and its surrounding area (including the Villa Medici) are the responsibility of the French State.

In 1494, Saint Francis of Paola, a hermit from Calabria, bought a vineyard from the papal scholar and former patriarch of Aquileia, Ermolao Barbaro, and then obtained the authorization from Pope Alexander VI to establish a monastery for the Minimite Friars. In 1502, Louis XII of France began construction of the church of the Trinità dei Monti next to this monastery, to celebrate his successful invasion of Naples. Building work began in a French style with pointed late Gothic arches, but construction lagged.

The present Italian Renaissance church was eventually built in its place and finally consecrated in 1585 by the great urbanizer Pope Sixtus V, whose via Sistina connected the Piazza della Trinità dei Monti (outside the church) to the Piazza Barberini across the city. The architect of the facade is not known for certain, but Wolfgang Lotz suggests that it may have originated in a design by Giacomo della Porta (a follower of Michelangelo), who had built the church of Sant'Atanasio dei Greci, which has similarities, a little earlier. The double staircase in front of the church was by Domenico Fontana.
