The Acropolis would be the main reason of your visit to Athens as a tourist. This enduring historical landmark has lived through triumphs, celebrations and catastrophes since the 5th century. The Parthenon known as the most important monument until today, has been a pagan place of worship, a mosque and a church for Christians.
Today, it is still standing grand with what is left for us to appreciate. The restoration of the Acropolis started in 1975 and is still ongoing. Aside from ancient buildings and theatres, sights of scaffolding and slab of marbles surround the area like a concrete jig saw puzzle waiting to be completed.
I visited the Acropolis twice during my visit, first I paid and on the second time for free, as the museums in Greece are free every first Sunday from November 1st to March 31st. To check if you are entitled for reduced prices visit this link: http://odysseus.culture.gr
