Acropolis of Athens
It’s the site that rules over all others on the city’s skyline; atop a sheer-sided cliff, this ancient citadel is home to some of the most important surviving buildings of the ancient Greek civilisation. The innate defensive qualities of the Acropolis hill have allowed the Parthenon, the Erechtheion and the Temple of Athena Nike to remain partially intact, despite the countless invasions and revolutions that have taken place in Greece since they were built.
