Norman Castle, Medieval fortress in Salemi, Italy.

Norman Castle in Salemi is a fortress built on a hilltop with a trapezoidal floor plan and multiple corner towers plus one tall cylindrical tower facing southwest. The structure provides views across the surrounding landscape and reflects the military design typical of medieval Norman architecture.

The castle was founded in 1077 during Norman rule and later rebuilt in the 13th century by Frederick II of Swabia to strengthen its defenses. These renovations made it one of the most important fortifications in the region.

The castle has housed Salemi's municipal museum since 2002, displaying archaeological finds from beneath the castle and elsewhere in the town. Its name recalls the builders: Roger I of Hauteville began it in 1077, and Frederick II of Hohenstaufen gave it its present form in the 1220s-1230s. Concerts are held in the museum hall.

The grounds are accessible during daytime hours on most weekdays and reached by walking up from the town center. Visitors should wear comfortable shoes since exploring the site and accessing the hilltop involve walking.

In 1860 during Italy's unification war, Giuseppe Garibaldi raised the Italian flag from this tower and declared Salemi the nation's capital for a single day. This unexpected moment of national importance often surprises visitors who discover it.
