The Rock Arch
The Rock Arch was an arched mountaintop between the Triple Peninsula of Chalkidike and the Unexplored Mount Pangeon in Makedonia, Greece.
Below the arch laid an ancient, forgotten tomb, which was used as a hideout by the Persians Darius and Natakas around 429 BCE. The Spartan misthios Kassandra met them there, and she also climbed up to the rock arch to take in the view.[1]
