Visiting Athens is like taking a step back in time, a wonderful history lesson that is great for all ages. Whether you have one, two, or more days in this city, here are the best things to do in Athens!

1. Acropolis, this 2.500-year-old rocky outcrop perched in Athens’ modern metropolis is the sight you’ve only dreamed about. The Acropolis finds itself at the very top of our list because if you do one thing in Athens, it has to be this.
2. Acropolis New Museum, an archeological museum that houses the artifacts found on the Acropolis and the surrounding slopes.
3. Tomb of the Unknown Soldier, located in Syntagma Square near the Hellenic Parliament Building, this is a war memorial that is dedicated to the Greek soldiers who died in war. The tomb is guarded by an Evzone soldier dressed in traditional uniform.
4. Panathenaic Stadium, a historic stadium where a lot of big events have occurred. It is also the site of the finish line for the Athens Classic Marathon.
5. Ancient Agora & Temple of Hephaestus, an archaeological site located near the Acropolis. For 5,000 years, this area was used as a marketplace, gathering place, and residential area. The ground of this large site is littered with the ruins of buildings and walkways. However, there are two important places to visit (the Temple of Hephaestus and the Stoa of Attalos).
6. The Roman Agora, just a short distance away from the Ancient Agora. This market and collection of buildings was built in the first century BC during the rule of Julius and Augustus Caesar. The main entrance is through the Gate of Athena. The Tower of the Winds is considered to be the world’s first meteorological center, featuring a sundial, water clock, and wind vane.
7. Hadrian's Library, an impressive monument in ancient Athens, constructed in 132 AD under the rule of Roman Emperor Hadrian. It was built to house rolls of papyrus books.
8. Temple of Olympian Zeus, built to honor Zeus and planned to be the greatest temple in the ancient world. When finished, it was one of the largest ever of the ancient temples, with 104 unusually tall columns, each 17.25 meters tall.
9. Temple of Poseidon, this temple at Sounion, which is dedicated to the mighty Poseidon, should be one of the first temples on your checklist.
