Grevenburg castle was built in 1350 by Count Johann III of Sponheim-Starkenburg and replaced Castle Starkenburg as the residence of the Rear County of Sponheim. With the extinction of the ruling male line of the Rhenish branch of the House of Sponheim in 1437 the castle became seat of the bailiff of the new Counts to Sponheim.
In 1680 it was conquered by Louis XIV of France and was extended, together with the fort of Mont Royal in the horshoe bend of the Mosel north of the town of Traben-Trarbach as a part of the fortifications. During the War of the Spanish Succession (1701–1714), in 1702 it was taken by the French under Taillardin and in 1704 on the express orders of the commanding officer John Churchill, 1st Duke of Marlborough it was overpowered by Friedrich das Wehrschloss. The badly damaged castle was then occupied by the Dutch. In 1730 it was repaired by the Electorate of Trier for the defence of Koblenz and the Rhine river. In the War of the Polish Succession it was taken after three weeks' siege for the fourth and last time by the French who destroyed it in July 1734. The castle was blown up, huge chunks of it have plunged into the valley beneath.
Of the castle, although only the western wall of the former keep remains, the foundations are largely intact.
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.
