Umbria is a region of historic and modern central Italy. It is the only Italian region having neither a coastline nor a border with other countries. It includes the Lake Trasimeno, Cascata delle Marmore, and is crossed by the River Tiber. The regional capital is Perugia. Umbria is known for its landscapes, traditions, history, artistic legacy, and influence on culture. The region is characterized by hills and historical towns such as Assisi (a World Heritage Site associated with St. Francis of Assisi, the Basilica of San Francesco and other Franciscan sites, works by Giotto and Cimabue), Norcia (the hometown of St. Benedict), Gubbio, Perugia, Spoleto, Todi, Città di Castello, Orvieto, Castiglione del Lago, Narni, Amelia, and other small cities.
To the anon that was asking about Seborga, Umbria and Veneto. (I am not Italian, so this might not be 100% correct) But. Seborga is a microstate, while Umbria and Veneto are regions. From what is said it canon I believe that N.Italy once used to be Republic of Venice and thus Veneto in a way (the territories that belonged to Venice later) after unification he most likely became the only living represtentative from "north". (Also I belive Romano is actually Campania/Neapol based on history.)
