The Acropolis of Athens is a fortified limestone hill rising approximately 150 meters above sea level in central Athens. Occupied since the Neolithic period, it developed into a major Mycenaean citadel in the Late Bronze Age before becoming the principal religious sanctuary of the city dedicated to Athena. During the 5th century BCE, under the leadership of Pericles, the plateau was transformed into a monumental sacred complex including the Parthenon, Propylaea, Erechtheion, and Temple of Athena Nike. The site continued to function through Hellenistic, Roman, Byzantine, and Ottoman periods, undergoing successive religious and structural transformations. Today it represents one of the most studied architectural and political landscapes of the ancient Mediterranean.

Prehistoric and Mycenaean Citadel
Neolithic – 12th century BCEArchaeological evidence indicates habitation on the Acropolis hill as early as the Neolithic period. By the 13th century BCE, it had been fortified as a Mycenaean citadel, surrounded by cyclopean walls. A palace complex likely stood near the later Erechtheion.
Archaic Sanctuary
8th–6th century BCEFollowing the collapse of the Mycenaean system, the Acropolis evolved into a religious center. Early temples dedicated to Athena Polias were constructed, including the so-called 'Older Parthenon.' Many votive statues from this period were buried after the Persian destruction of 480 BCE.
Classical Reconstruction Program
447–406 BCEAfter the Persian Wars, Athens initiated an extensive rebuilding program under Pericles. The Parthenon (447–432 BCE), Propylaea (437–432 BCE), Temple of Athena Nike, and Erechtheion (421–406 BCE) were constructed, redefining the plateau as a monumental architectural ensemble that reflected Athenian imperial ambition.
Hellenistic and Roman Periods
323 BCE – 4th century CEThe Acropolis retained its sacred function under Macedonian and later Roman rule. Roman emperors, including Augustus and Hadrian, contributed dedications and restorations. The architectural core remained largely intact during this period.
Christian and Ottoman Transformations
5th–19th centuryIn Late Antiquity, major temples were converted into Christian churches. Following the Ottoman conquest in 1458, structures were adapted for Islamic use, and new buildings were added. In 1687, a Venetian bombardment caused severe damage, particularly to the Parthenon, which was being used as an ammunition store.
Modern Archaeology and Conservation
19th century – presentAfter Greek independence in 1830, Ottoman-era additions were removed as part of a national restoration effort emphasizing the Classical phase. Systematic excavation and conservation began in the 19th century and continue today under the Acropolis Restoration Service, focusing on structural stabilization and anastylosis using original materials where possible.
