The Sarajevo tunnel was constructed by the citizens during the siege that took place between 1992 and 1995. Serbian forces had entirely cut off the city and this tunnel served as a link between the neighbourhoods Dobrinja and Butmir. This enabled food and aid to come in, and people to get out.

Traces of the old city walls can still be found all around Zadar, with some sections dating back to the Middle Ages and a greater part built during the Venetian control over the city as a fortification against the Turks. Beside some portions of the previous walls, eight gates used as entrances to the city remain, of which the most elaborate is the one known as Land Gate. Located just in front of the little Foša harbour, Land Gate is adorned with some of the finest Dalmatian Renaissance-style decorations, including representations of Saint Chrysogonus and the lion of St Mark.
