Lazzaretto of Ancona

The Lazzaretto of Ancona, also called the Mole Vanvitelliana, is a pentagonal 18th-century building built on an artificial island as a quarantine station for the port town of Ancona, Italy. In 1732, Pope Clement XII commissioned Luigi Vanvitelli to build the Lazzaretto. Vanvitelli designed it in the shape of a regular pentagon, which is the shape that characterizes the entire structure, from the surrounding walls to the buildings and the central square. It is now a cultural centre and houses art exhibitions, a tactile museum (Museo Omero) and an auditorium.
