San Nicandro castle as we see it today dates from the 15th century although it was built on the site of a much more older fortress dating from the Norman and Swabian periods.
The castle is trapeze shaped with four corner towers, and was renovated during the 17th century. On the north side there are two square towers, one of which is one of the original towers, while on the south side there are two round towers built by the Aragonese which are behind the church.
The castle, which was actually built as a mansion, was the usual residence of the Della Marra and all the vassals of San Nicandro Garganico until the time of the Cattaneo Princes. In the 16th century the castle was integrated with the gateway to the east and the lodge was built that connected the castle with a large palace built between the door and the walls of the castle.
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.
