From the Wikipedia page on the Villa Mondragone .
Villa Mondragone is a patrician villa originally in the territory of the Italian commune of Frascati (Latium, central Italy), now in the territory of Monte Porzio Catone (Alban Hills). It lies on a hill 416m above sea-level, in an area called, from its many castles and villas, Castelli Romani about 20 km (12 mi) southeast of Rome, near the ancient town of Tusculum.
Stated locality where the Voynich Manuscript was found, and acquired, presumably having been transferred there with other material owned by Petrus Beckx, 22nd Superior-General of the Society of Jesus, following the unification of Italy. Wilfrid Voynich sometimes suggested different locations, but, like other antiquarian booksellers (and similar professions) would have reason to be somewhat obscure about where he obtained his material.
It is otherwise possibly best known for Pope Gregory XIII’s, issuing of the Papal Bull "Inter gravissimas" (Wikipedia page ), which initiated the reform of the calendar now in use and known as the Gregorian calendar (Wikipedia page ).
In 1620, the owners of the villa bequeathed the Mondragone library to the Vatican library.
In 1865 the Jesuits turned it into a college, the Nobile Collegio Mondragone, for young aristocrats, which operated until 1953. In 1981 it was sold by the Order of the Jesuits to the University, where as of modern times, the Villa remains a peripheral seat of the University of Rome Tor Vergata.
In the early years of the 20th century the Jesuits in the Villa were short of funds and discretely selling some of their holdings: Wilfrid Voynich was to buy a number of volumes in 1912, including the manuscript that became known by his name.
