Acropolis

This ancient citadel, built in the fifth century B.C., towers over the city and is home to some of the most impressive ancient ruins, buildings, and artifacts. The most famous temple, the Parthenon, was dedicated to the goddess Athena and is considered the peak of Greek art. You can avoid long lines by joining a walking tour of the site. Make sure to wear comfortable shoes and bring sunscreen, as the walk up the hill can be steep and exposed to the sun. For the best experience, visit early in the morning or late in the afternoon to avoid the heat and for fewer crowds. – Tripadvisor
