The Lazzarettos of Dubrovnik is a group of interconnected buildings located 300 meters away from the walls of Dubrovnik that were once used as a quarantine station for the Republic of Ragusa.

A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control.
