The inscription IOAN. ANTINORIO CAMERTE ARCHIT. at the base of the obelisk in Piazza Montecitorio serves as a permanent architectural signature for an Italian surveyor who transitioned into a significant career in Rome. Operating between 1734 and 1792, his professional trajectory spanned from local projects in Camerino to intense urban interventions for the papacy.
Formative years and the Lisbon period
Born in 1734 in Camerino, Giovanni Antinori initially studied mathematics under his father, Girolamo, a surveyor. He eventually moved to Rome, attending the Sapienza and the Accademia di San Luca. His early exposure to the field included training under Marquis Gerolamo Theodoli. In 1755, Antinori traveled to Lisbon to assist in reconstruction efforts following the 1755 earthquake. His time in Portugal ended abruptly after he was imprisoned, requiring an escape aided by Josefa Luisa Lopez de Cunha, whom he subsequently married.

Upon returning to Italy, Antinori executed various private commissions, including an arcade and Hall of Mirrors for Marquis Alessandro Bandini in Lanciano di Castelraimondo. Between 1772 and 1778, he oversaw the interior reconstruction of the Monte Oliveto Maggiore abbey, incorporating Baroque elements that hinted at his later neoclassical output. He maintained a long-standing relationship with the Doria-Pamphilj family, beginning with temporary structures for the 1769 visit of Emperor Joseph II. He later worked on garden features at Villa Doria Pamphili and built a casale at Piombinara for the family between 1778 and 1783.
Papal service and obelisk projects
Under the authority of Pope Pius VI, Antinori directed significant engineering feats in Rome. His work at the church of San Rocco uncovered a large red granite obelisk, which he later re-erected in the Piazza del Quirinale between the Horse Tamers. His technical expertise in using winches and lifting mechanisms allowed him to position the Sallustian obelisk in 1787 and the Montecitorio obelisk between 1790 and 1792. During this period, he also drafted a proposal for the Palazzo Braschi, though the commission was eventually awarded to other architects.
Final years and legacy
Antinori died in Rome in 1792 while still supervising the installation of the obelisk at Piazza Montecitorio. The project was completed by his assistant, Pasquale Belli. He was buried in the Church of S. Venanzio dei Camerti. Although the church was demolished in 1929 to clear space for the Vittorio Emmanuele Monument, the obelisks he handled remain central features of the Roman landscape, standing as practical monuments to his technical contribution to the city's urban topography.
