The name Martinitt refers to a historical boy orphanage of Milan, Italy, that was established in the 16th Century, now part of Pio Albergo Trivulzio, a public Milanese institution that provides aid to needy orphans, elders and other people experiencing social difficulties. The name comes from Saint Martin, as the orphanage was originally based in the eponymous oratory. The orphan boys themselves were thus referred to as "Martinitt", a plural of "Martinett" ("little Martin") in Lombard language. The Martinitt played an important role in the history of Milan, most notably in the Five Days of Milan.
