Parthenon

An impressive symbol of Classical Greece, the Parthenon is a cultural landmark like no other. A temple that served different functions over the course of its existence, the Parthenon has had several incarnations. At one point is served as a treasury and at another it was even a Christian church. Now it's a must-see sight and the unchallenged highlight of visiting the Acropolis (and for some, Greece in general).

Tickets to visit (but not enter) the Parthenon are available for purchase at the site, which is located next to the Odeion of Herodes Atticus on the southern slope of the Acropolis. Plan to visit in the early morning, before the crowds and (and the heat, depending on the time of year) become insufferable.
