Saint Ivan Fortress (DUBROVNIK)

3D Model

One of the key forts in the Dubrovnik City walls defense complex is most certainly the Fortress of St. John, often called Mulo tower. It is a complex monumental fortress located on the south-eastern side of the old city port, controlling and protecting the entrance of the port. The fort was built as a consequence of many upgrades of the port defence system. The side toward the sea is round and lower part of the wall is inclined, while the part facing the port has flat vertical walls.

In 1346 Dubrovnik government concluded to build a fort on the outer dock of the port ­ Dock Fort. The building started that year and lasted for several years. This fort is still visible as a integral part of St. John fortress. The outline of this initial fort is visible on the western wall of St. John fortress. This initial fort was connected with the City with a defensive wall and the gates passing through those walls (Croatian ­ “Vrata mula” ­ Dock Gates).
