At the foot of the sacred and gold-bearing Mount Pangaion, where myths meet history, Dionysus meets Orpheus, Phyllis meets Demophon, son of Theseus, the Nine Muses meet the god Strymon, the Persians meet the Greeks, the ancient Thracians meet the Athenians and Spartans, Alexander the Great meets his vision, the Macedonians meet the Romans, the ancient Via Egnatia meets the new one, and the “Nine Roads” meet ancient Amphipolis…. we chose to establish our business, at this gateway to the Prefecture of Serres, offering our visitor modern and comfortable spaces, a playground, a park with small birds and animals, wonderful local traditional products, and warm hospitality.

As he advanced (Xerxes) towards the west, he passed through the regions of those who dwell north of Pangaion… he reached the river Strymon and the city of Eion. This region around Pangaion is called Phyllis, it extends west to the river Angitis, a tributary of the Strymon, and south to the Strymon itself.

After making these sacrifices and many other incantations for the river, they proceeded to the place called Nine Roads, which belongs to the Edonians… when they learned that the place was called Nine Roads, they took nine young men and nine young women from the local population and buried them alive…

In this location, where the city is today, Aristagoras of Miletus had tried to build a city even earlier... but was repulsed by the Edonians. Thirty-two years later, the Athenians also sent ten thousand settlers there... who were, however, slaughtered at Drabeskos by the Edonian Thracians.
