Lentorama 2026: Hic es: aedificia Vaticani

Day 19: Torre Gregoriana

The Gregorian Tower, also known as the Tower of the Winds, is unique in that it's a building built on top of other buildings. Constructed between 1578 and 1580, the two-story tower in on top of the Gallery of Maps that is part of the Vatican Museum. It served as an observatory, as the planned Gregorian calendar reform would involve a number of astronomical observations.

Outside of a period in the 19th century, the tower (now actually two towers) has served as an observatory, though is now more of an historical site. It also features some 16th century Flemish frescoes, and was once the residence of Queen Charlotte of Sweden after she converted to Catholicism.
