The area, in which today Neos Pyrgos is found, constituted in the past, one part of the resplendent city of Orei and the harbour of Istiea with ist more than 20. According to the Greek and foreign archaeologists, this harbour was located where today unfolds the small beautiful beach of Nissiotissa (one kilometre off westwards from Neos Pyrgos).
Residency n this region begins, as in the other cities of ancient Istiea, from the Neolithic age. An important discovery of archaic cluster was made a few years ago in the region of Neo Pyrgos. It pictured the battle between Hercules and the lion, which today is found for maintenance in the Archaeological Museum of Eretria.
The beautiful costal city, seen today, is the creation of refugees, which in 1926 arrived here from the city of Pyrgos in Constantinople,, transforming the unpleasant and completely deserted region to a genuine paradise,, as the visitor also understands from the first impression. In the beach of Nisiotissa, just some metres off the beach, a small rocky island is found, almost as an extension of the land, accordering to the German archaelogost of the previous century, these should be the ruins of the ancient harbour. the ruins that are visible on the top of the small island belong to a post Byzantine building. accordering to others, the old building was a small church or a small tower of the Frankish dominion and accordering to others perhaps a windmill of that period.
Today's Neos Pyrgos, just like Orei, has a wide variety of taverns, clubs and cafeterias, as well as naturally beautiful and spotless beaches.
