The travellers' Lodge or the quarantine is a medieval building joined to the city gate. It is possible to determine its function on the basis of a fresco of St. Christopher, who was the patron saint of travellers and the poor. The building had the ground-floor and the upper floor and itr was very solidly built. The ground floor was accessed through two arched openings. On the eastern side there was a semi-circular vaulted chamber whose purpose is not clear but which was certainly built in the Middle Ages. This can be determined on the basis of a few graffity engraved in fresh mortar. What was inscribed were proper names: PETRUS ARNO, MARCUS DE PRIULI...
This building was later turned into a mesdzid and the remaining space was used for graves
The building (22) could also have been a place where travellers took rest before entering the city. It might have been a kind of  an inn or a coffee-house, together with the Municipial Loggia, because it is located in front of the lower gate built in the late Middle Ages. The building has one of the most beautiful porticos in the city shaped as semicircular arcades which were made during the Ottoman rule when the medieval building was adapted.
