Frýdlant castle complex consists of the Gothic castle with a high tower and a Renaissance château. There are exhibits, such as of Albrecht von Wallenstein, the Thirty Years' War, and an armoury of 1,000 weapons used for military and hunting. The castle includes the Chapel of Saint Anne, the Knights' Hall, rooms for the count and countess, and a working kitchen.
In the 13th century the castle was held by the Ronovci family until the middle of the century when Častolov of Ronov was forced to return the castle and other properties to King Ottokar II. The first written mention of Frýdlant is from 1278, when Rudolf of Bieberstein, purchased the castle and surrounding land from the king.
Frydlant castle and town went to Emperor Ferdinand I when Christopher, the last of the line of the Birbsteins, died in 1551. The castle went into the Redern family when Bedřich bought it in 1558. Several new villages were established and the production of linen cloth resulted in an economic boom during the initial years of the Redern family. Marco Spazzio di Lancio, an Italian architect hired by the family, expanded the castle in the 16th century.
At the end of the Thirty Years' War, the castle was possessed by the Swedes. They constructed fortified barbicans and strengthened the defensive walls.
In 1800 or 1801, the Clam-Gallas family opened the castle to the public as a museum.
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.
