Delphi is an ancient Greek city located in the central part of Greece on the southwestern slope of Mount Parnassus. In ancient times, Delphi was known as the site of the Delphic oracle, the most important oracle in the classical world. People from all over Greece and beyond would come to Delphi to consult the oracle for advice on important matters such as war, politics, and personal matters.

The sanctuary of Delphi includes the Temple of Apollo, where the oracle was located, the treasuries, where the offerings to the gods were kept, the theater, and the stadium. The site is also famous for the impressive remains of the Tholos, a circular temple that housed the Pythian games, and the famous bronze statue of the Charioteer of Delphi.

The archaeological site of Delphi was declared a UNESCO World Heritage Site in 1987. Today, visitors can explore the site, see the ruins of the ancient city and the Temple of Apollo, and learn more about the history and significance of the Delphic oracle at the onsite museum. The site is a popular tourist attraction and an important part of Greek history and culture.
