The Lazzarettos of Dubrovnik (Croatian: Dubrovački lazareti) 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. Republic of Ragusa was an active merchant city-state and was thus in a contact with people and goods from all over the world so it had to introduce preventive health measures to protect its citizens from various epidemics which broke out in countries across the Mediterranean and the Balkans due to poor hygiene. On July 27, 1377, the Great Council of the Republic adopted a decree which introduced a quarantine as a measure of protection against the spread of infectious diseases by which all merchants, sailors, and goods arriving from "suspicious lands" could not enter the city if they haven't spent a month in a quarantines which were on the remote, uninhabited islands of Mrkan, Bobara and Supetar.
