Delphi became super important around 2,700 years ago as a special shrine where people asked the oracle for advice. Greek cities from everywhere visited, making it a meeting spot for all Greeks, called pan-Hellenic.
Over centuries, different groups controlled it—like the Phocians, Athenians, and later the Macedonians and Romans. There were quarrels, called sacred wars, but the site stayed holy. Emperors visited, and it thrived until the 300s AD, when a Roman leader closed pagan temples.
Forgotten for ages under Ottoman rule, explorers in the 1400s and later dug it up, revealing its wonders for us today.
