Fort Revelin, 16th century fortress in Dubrovnik, Croatia

Fort Revelin is a detached fortress northeast of Dubrovnik's city walls, separated from them by a deep moat and linked by a bridge. Its irregular quadrilateral plan ends in a sharp northeast corner, and the interior is divided into three large vaulted rooms.

A first record of the need for a fort here dates from 1449, and construction began in 1463 against the Ottoman threat. In 1538 the Council accepted Antonio Ferramolino's model for a massive detached fortress with an irregular quadrilateral plan and a sharp northeast corner. Building started the next year and was completed in 1551, with all other construction in the city halted to finish it.

The fortress serves as a cultural venue where outdoor performances and concerts take place on its large stone-paved terrace. These events connect the site to the rhythm of contemporary city life and draw both locals and travelers.

The fortress is easily reached by stairs and footpaths, offering clear views over the harbor from multiple vantage points. Visitors should know that some paths atop the structure can be narrow and sturdy footwear is advisable.

The fortress survived the catastrophic 1667 earthquake intact while much of the surrounding city lay in ruins. This structural strength made it a crucial safe haven for the city's most valuable possessions.
