Palace of Gregory XIII
The Palazzo di Gregorio XIII is an integral part of the Apostolic Palace and partially encloses the famous Cortile di San Damaso. Built during the pontificate of Gregory XIII (1572-1585), this building marks a phase of significant scientific and architectural expansion in the Vatican. A prominent feature of this wing is the Torre dei Venti (Tower of the Winds), which was used for astronomical observations and played a key role in the Gregorian calendar reform of 1582. The architecture of the palace is characterized by elegant loggias, partially decorated by famous artists such as Giovanni da Udine. These galleries served as representative connecting paths and offer spectacular views of the courtyard and the city of Rome. Historically, the palace was a center for diplomacy and science, frequented by eminent scholars of the time. The facades harmoniously integrate classic Renaissance style elements and pave the way for later expansions under Sixtus V. Today, the complex houses various administrative departments of the Curia and remains a testament to the intellectual ambition of the Catholic Church in the 16th century.
