The Revelin Fortress: Dubrovnik’s Shield Against the Ottomans

Located northeast of Dubrovnik’s city walls, the fortress stands detached from the main perimeter, partially integrating into the defensive complex of the Ploče Gate—the main eastern entrance to the city. A deep moat was excavated around it, and a bridge connected it to the town, providing an additional layer of defense in the event of an attack.

Early Construction and Earliest Depictions

The need for a fortification at this specific location was first raised as early as 1449, when the Dubrovnik authorities assessed that the eastern approach to the city was particularly vulnerable. The first phase of construction began in 1463, during which the lower section of the fortress was built.

What this early phase looked like can be seen in the famous depiction of Dubrovnik held in the hands of Saint Blaise on a triptych by painter Nikola Božidarević, created around 1500. This artwork serves as an invaluable visual source for the city’s appearance at the turn of the 16th century.

The Great Renaissance Reconstruction of the 16th Century

With the rapid advancement of artillery in the 16th century, Dubrovnik’s authorities decided to further reinforce the city’s fortifications. The pivotal reconstruction of the fortress took place in 1538, when the Italian military engineer Antonio Ferramolino of Bergamo was hired.

Under his direction, the existing structure was reshaped into a powerful Renaissance fortress with an irregular quadrilateral layout, featuring a sharp, pronounced angle facing any potential attacker. This design allowed for a more effective defense and better control over the area in front of the city gates.

The model for the new fortress was officially approved on December 30, 1538, by Dubrovnik’s state council, known as the Consilium Rogatorum (Council of the Requested), and construction began the following year. Completed in 1551, Revelin became one of the most modern fortifications in Dubrovnik.

During its construction, a regulation was introduced requiring anyone entering Dubrovnik to bring a single stone with them. The size of the stone had to match the physical strength of the person carrying it. Through this rule, visitors symbolically contributed to building the city’s defensive system.

Architecture and Defensive System

Revelin Fortress features three entrances, and its defensive layout was extraordinarily well thought out. As a detached fortification, it was surrounded by a moat and the sea on three sides, significantly hindering enemy approach.

Its massive stone walls and robust bastion design were specifically engineered to withstand artillery fire—a hallmark feature of Renaissance military architecture. The spacious interior of the fortress was used to house military equipment and defensive supplies.

This space also served as the workshop for Ivan Krstitelj Rabljanin (John the Baptist of Rab), a renowned Renaissance cannon and bell founder, who operated his casting furnaces within the fortress. His work was vital to Dubrovnik’s defensive needs throughout the 16th century.

Revelin After the Great Earthquake

The catastrophic Dubrovnik earthquake of 1667 devastated a large portion of the city. However, Revelin Fortress suffered relatively minor damage thanks to its massive construction.

Due to its safety and structural stability, the fortress took on a new function in the wake of the disaster. The state treasury of the Republic of Ragusa (Dubrovnik) and the treasury of the Dubrovnik Cathedral were temporarily relocated here. It also served as the administrative center of the Republic for a time while the city was gradually being rebuilt.

Revelin Today

Today, Revelin Fortress no longer serves a military purpose, but it remains one of Dubrovnik’s most vibrant cultural spaces.

The fortress’s expansive terraces host various performing arts events during the famous Dubrovnik Summer Festival, which transforms the city’s historic sites into stages for theater, music, and dance each year. The interior of the fortress is regularly used for concerts, cultural programs, and various events.

Game of Thrones

Revelin Fortress was not one of the primary filming locations for the Game of Thrones series. Unlike some of Dubrovnik’s other fortifications, it does not appear in clearly recognizable scenes. However, because it sits right next to areas frequently used for filming, it occasionally appears in the background of panoramic shots of the city depicting King’s Landing.
