Ancient Thera in Santorini, Greece.
Situated 360 meters high on Messavouno mountain, overlooking the vast Aegean Sea, Ancient Thera in Santorini, Greece, was a relatively unimportant city during its time and was named after the mythical ruler, Theras.
Common to all cities across Greece, the city was home to various theatres, shops, houses and even a gymnasium for exercise. What makes this city most impressive by today's standards is its construction site. Previously accessible only by steep inclines on the mountainside range, the site is now reachable by a very narrow, winding road that is not for the faint of heart when it comes to heights (especially for someone like myself, in particular!).
Historically, the city gained most of its exposure and importance when it was annexed and thus recommissioned by the Egyptians to serve as a naval base during the 4th Century BC (400 BC-301 BC).
