Acropolis of Athens

The Acropolis of Athens is the most influential architectural ensemble in Western history, anchored by the Parthenon—a temple to Athena completed in 432 BC that remains structurally intact despite 2,500 years of use as a church, mosque, and gunpowder store. The site draws 3.3 million visitors annually, making it the most photographed monument in Europe behind only the Eiffel Tower. Its claim as the foundation of classical architecture is supported by the Acropolis Museum, which houses 4,000 objects including the original Parthenon sculptures not removed by Lord Elgin. For historical impact and preservation, it outperforms #2 Santorini Caldera' s volcanic landscape because the Parthenon' s design principles have been replicated in buildings worldwide from Neoclassical capitals to modern government edifices.
