The Nové Hrady Castle was built in the first half of 13th century. It was damaged in 1573 by a gunpowder explosion and in 1590 by an earthquake. Complete demolition was considered, but only the ruins of the massive bergfried and the adjacent palace were demolished. The rest of the castle complex was repaired and newly fortified according to the design of the Italian architect Antonio Canevallo. The castle lost its function of the aristocratic residence in 1635 and in the following centuries it was used as a library, archive, administration and housing for officials. Today it is owned by the state. Since 2000, it has been open to the public and offers guided tours.
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.
