Kostianvirta battle was part of the Great Northern War (1700-1721). Russian army invaded to Finland in 1713 because the major Swedish army was fighting in central Europe. On October 1713, Finnish army under General Carl Gustaf Armfeldt had set the defence line to Kostianvirta river. When Russians attacked, Armfedlt’s 3,400 men first succesfully prevented 15,000 Russians to cross Kostianvirta.
On October 6, Russians made the landing coincidentally in Kostianvirta and near Mallasvesi and tried to besiege Finnish Army. Finnish soldiers were forced to withdrawn to the north. They lost 800 men and all nine cannons.
The monument of battle was erected in 1906. There are also reconstructed wooden trenches and remains of original defense structures.
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.
