The citadel's walls are designed to withstand direct cannon fire, a feature critical to its mid-16th-century defense strategy.
Thousands of fruit bats reside within the fortress, making it one of the most significant bat hibernation sites in Europe.
The Juliusturm is the oldest structure in the citadel and one of the oldest buildings in the entire Berlin area.
During the 19th century, the Prussian state treasury was stored in the Juliusturm to secure it during wartime.
The fortress was designed by Italian architect Francesco Chiaramella de Gandino to replace a medieval castle on the site.
It served as a detention site for high-profile prisoners, including officials of the Third Reich after 1945.
The site features a permanent exhibition titled 'Captured and Protected' that displays historical monuments and statues removed from public spaces.
Spandau Citadel is one of Europe's best-preserved Renaissance fortresses, located at the confluence of the Havel and Spree rivers. The site features the Juliusturm, a 13th-century keep that predates the surrounding 16th-century Italian-style bastions. The complex currently functions as a regional history museum and cultural center hosting temporary exhibitions in its former armory and barracks. It serves as a sanctuary for thousands of bats, which hibernate in the cellars during winter. The site includes a dedicated permanent exhibition tracing the citadel's military history and its former role as a prison. It remains a rare example of a star-shaped fortification that successfully retained its architectural integrity through centuries of warfare and urban development.
