The Altar of Zeus in Pergamon is one of the most iconic monuments of Hellenistic architecture, built in the 2nd century BCE. Known for its grandiose size and detailed friezes, it was dedicated to Zeus and Athena, showcasing the gods’ triumph over the Giants. The intricate reliefs, now displayed at the Pergamon Museum in Berlin, depict mythological battles in stunning detail. Though the altar’s original site in Pergamon remains as ruins, it provides a glimpse into the artistic and religious life of the ancient city.
