Duomo is a generic Italian term for a cathedral church. The formal word for a church that is presently a cathedral is cattedrale; a Duomo may be either a present or a former cathedral (the latter always in a town that no longer has a bishop nor therefore a cathedral, as for example Trevi). Such churches are usually referred to simply as "Il Duomo" or "The Duomo", without regard to the full proper name of the church.
