The Pergamonmuseum, one of Berlin’s most visited and controversial historical attractions, is a palatial three-wing complex that transports visitors to the ancient worlds of Babylon, Greece, Rome and beyond. With around 800,000 visitors each year, the museum houses an impressive collection of classical sculptures, monumental architecture and excavated treasures, including the radiant-blue Ishtar Gate from Babylon, the Market Gate of Miletus and the renowned Pergamon Altar. Since 2013, the Pergamon has been undergoing a €477 million (about $560 million) renovation and the central building, home of the Pergamon Altar and other works, will not reopen until 2025. In the meantime, visitors can experience a 360° panorama exhibition depicting how the museum and its altar would have looked in 129 BC.

The Pergamonmuseum's formation was part of Germany's 19th century archaeological mission to excavate ancient kingdoms. However, some artifacts are still being held in Russia, and in 2011, the 3000-year-old Sphinx of Hattusa was returned to Turkey, sparking debate concerning the legitimacy of the museum's overall acquisition.
