Acropolis @ Athens, Greece
This day truly felt like I was in a time warp and visited the ancient times. Couple photos from my GoPro Hero 3.
Travel tip: You really only need about 24 hours in Athens. The city is small and you want to make sure you stay in downtown Athens where all the shops, restaurants, and the ruins are. There really isn't much to see in Athens, but visiting Acropolis made traveling to this quiet little city definitely worth it.
