The church of the Santissima Trinità dei Monti, often called merely the Trinità dei Monti (French: La Trinité-des-Monts) is a 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 property of the French State.
