Lokrum Lazaretto
The great pandemic of bubonic and pulmonary plague, the so-called Black Death, was transferred from Asia to Europe in the 14th century. The first case was recorded on the island of Šipan, and the disease soon spread to the City itself. The Dubrovnik authorities were not allowed to disrupt the trade by closing the port and severing contact with the “outside world“. The wise people of Dubrovnik tried to continue trading, so the decision was made to keep people, cattle, ships and goods in isolation for forty days before entering the City. In 1377, the Grand Council decided to establish quarantine stations (lazarettos, lazarets), first in Cavtat and on the island of Mrkan, shortly after another in Bobara and Supetar, and in 1430 at Danče.
The decision to build a third quarantine station on the north side of Lokrum was made by the Dubrovnik Senate in 1534. This large lazaretto was never completed, and its remains are still visible today. The double walls of a square-shaped fortress were 100 m long and about 4 m high and had small rooms for people to stay on the inside with a fireplace in each of them. In the central courtyard was a cistern with drinking water. Over the northern entrance door, there was an inscription which ran: „Erected by the Dubrovnik senators in 1557 with the money collected from the wills of pious people. May almighty God keep it from perishing.“ It is presumed that a chapel dedicated to Saint Blaise, the patron saint of Dubrovnik, was built in front of the lazaret gates, or a statue was placed above the entrance and was later transferred and built into the City walls. These gates were walled up at the time of the construction of Fort Royal, and the new ones were opened in the east wall. Over time, the people of Dubrovnik realized that the lazaretto, if conquered, could serve the enemy as a strong stronghold from which the City and port could be endangered. In the meantime, in 1590 lazarettos were also built at Ploče, which, over time, proved to be the most practical. In 1647, the Dubrovnik Senate made a decision to use the stone of the Lokrum lazaretto for the construction of the City walls. In the area of the unfinished lazaretto, the Benedictines built an olive grove. A new gate was opened in the east wall and a house was built next to it for a guard who lived in an olive grove.
