The Battle of Vilnius was the first time a foreign power managed to capture a group of cultural, and historic structures on the left bank of what river?
Vilnius Castle Complex The Vilnius Castle Complex (Lithuanian: "Vilniaus pilių kompleksas" or "Vilniaus pilys" ) is a group of cultural, and historic structures on the left bank of the Neris River, near its confluence with the Vilnia River, in Vilnius, Lithuania. The buildings, which evolved between the 10th and 18th centuries, were one of Lithuania's major defensive structures.
Bock (Luxembourg) The Bock (Luxembourgish: "Bockfiels" ) is a promontory in the north-eastern corner of Luxembourg City's old historical district. Offering a natural fortification, its rocky cliffs tower above the River Alzette which surrounds it on three sides. It was here that Count Siegfried built his Castle of "Lucilinburhuc" in 963, providing a basis for the development of the town which became Luxembourg. Over the centuries, the Bock and the surrounding defences were reinforced, attacked and rebuilt time and time again as the armies of the Burgundians, Habsburgs, Spaniards, Prussians and French vied for victory over one of Europe's most strategic strongholds, the Fortress of Luxembourg. Warring did not stop until the Treaty of London was signed in 1867, calling for the demolition of the fortifications. Ruins of the old castle and the vast underground system of passages and galleries known as the casemates continue to be a major tourist attraction.
