The Church of the Madonna dell’Archetto, also known as the Santuario della Madonna dell’Archetto, is a minor Roman Catholic church located in Rome, Italy. Situated in the rione Trevi, it is one of the city's smallest churches, renowned for its intimate size and exquisite 19th-century architecture. The church was designed by the architect Virginio Vespignani and consecrated in 1851. It houses a venerated Marian icon, the "Madonna dell’Archetto," which is attributed to the early 17th century. This church is particularly noted for its elegant interior, featuring vibrant frescoes by Constantino Brumidi, who later became known for his work on the United States Capitol. Despite its modest proportions, the Church of the Madonna dell’Archetto remains a cherished site of devotion and a hidden gem in the heart of Rome.
