Italian architect. He designed the elegant façade of the Palazzo delle Assicurazioni Generale, Piazza Venezia, Rome (1902–7), and, as Superintendent of Monuments in Ascoli Piceno and Umbria (1891–1905), he carried out many works of preservation and renovation in those regions and in Rome itself. He reconstructed the Church of San Francesco, Force, Ascoli Piceno (1878–83), and restored the Cathedral of Sant'Emidio, Ascoli Piceno (1888–90), among many other buildings. He is remembered primarily for the gigantic Neo-Classical monument to Vittorio Emanuele II (1820–78—King of Sardinia and (from 1861) King of Italy), a huge pile-up of masonry (known by irreverent Romans as ‘The Typewriter’) dwarfing the Capitoline Hill in Rome, much altered after Sacconi's death by others, including G. Koch and P. Piacentini. Among his other works may be cited the quadriportico of San Paolo fuori le Mura, Rome (1893–1910—with Calderini), the tomb of the assassinated King Umberto I (reigned 1878–1900) in the Pantheon, Rome (completed 1910), and the Expiatory Chapel in memory of the murdered King in Monza (1910).
