Ancona, a province, a town and a port in Marches, Italy, on the Adriatic Sea. The name comes from Greek (and means "elbow").
The town is finely situated on and between the slopes of the two extremities of the promontory of Monte Conero, Monte Astagno, occupied by the citadel, and Monte Guasco, on which the Duomo stands.
Among the many monuments, the Lazzaretto (Laemocomium or "Mole Vanvitelliana"), planned by architect Luigi Vanvitelli in 1732. It is a pentagonal building covering more than 20,000 sq.m., built to protect the military defensive authorities from the risk of contagious diseases eventually reaching the town with the ships. Later it was used also as a military hospital or as barracks.
