Schachenstein Castle was the last hill castle to be built in the Styria. It was built in 1464 by Abbot John II Schachner of Lambrecht as a summer residence and lordly manor. It was extended in 1630 and 1740. From the end of the 18th century the castle lost its significance and fell into ruins.
The main purpose of the fortification was as a home and summer residence of the abbots of St. Lambrecht's Abbey as evinced by a large number of historic records. Subsequently, it was used to seal off the Mariazell road and protect the population of the Aflenz valley - who were looked after by the abbey - as well as providing a refuge during Turkish and Hungarian invasions.
The site of castle was an outstanding choice: some 640 above sea level on rocks forming the southern spur of the Schöckelberg. It is situated on an easily defended constriction of the road from Einodgräben to Mariazell, which was originally also guarded by a fortified gateway.
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.
