Mount Fokas is a 862m high hill in in the area of Corinth. A medieval settlement existed on its trapezoid summit and later a castle was built by the Franks in the 13th century (or perhaps by the Byzantines, a little earlier).
The castle controlled the plains of Nemea and the main route to the center of Peloponnese. It had visual contact with other Frankish castles in the area like Acrocorinth or Agios Vasilios but also with some castles in Central Greece, on the opposite side of the gulf of Corinth.
Only a few ruins of the walls and from the settlement remain at the lower part of the rock.
References:Stobi was an ancient town of Paeonia located near Gradsko. It is considered by many to be the most famous archaeological site in North Macedonia. Stobi was built where the Erigon (Crna River) joins the Axios (Vardar), making it strategically important as a center for both trade and warfare.
Stobi developed from a Paeonian settlement established in the Archaic period. It is believed that in 217 BCE, Philip V annexed Paionia during his campaign against the Dardani who had entered Bylazora, the largest Paeonian town.
The city was first mentioned in writing by the historian Livy, in connection with a victory of Philip V of Macedon over the Dardani in 197 BC. In 168 BC, the Romans defeated Perseus and Macedonia was divided into four nominally independent republics. In 148 BC, the four areas of Macedonia were brought together in a unified Roman province. In the reign of Augustus the city grew in size and population.
