Julius Tower

The Spandau Citadel (German: Zitadelle Spandau) is a fortress, one of the best-preserved Renaissance military structures of Europe. Built from 1559–94 atop a medieval fort on an island created by the meeting of the Havel and the Spree. In recent years it has been used as a museum and has become a popular tourist spot.
