Pope Gregory XIII (Ugo Boncompagni, 1502–1585) commissioned the Gregorian calendar, in use to this day. He built the Vatican's Tower of the Winds (Gregorian Tower) which included a meridian room, set up to demonstrate the need for this reform. This project was the first of a series of astronomical observatories sited at the Vatican.Naming citation (WGSBN Bull. 3, #2, 15), IAU / Minor Planet Center, via NASA/JPL
