Lower Saxony is Germany's second-largest state by area, stretching from the North Sea coast and the East Frisian islands down through rolling farmland to the forested Harz mountains on its southern border. Its capital, Hannover, is best known for the Herrenhausen Gardens and a compact, walkable Old Town, but the state's UNESCO credentials lie elsewhere: the Romanesque churches of Hildesheim, the thousand-year Rammelsberg silver mine above Goslar, and the vast tidal mudflats of the Wadden Sea along the coast. Half-timbered towns like Celle and Lüneburg preserve centuries of Hanseatic and salt-trading wealth, while Wolfsburg's Autostadt and the university town of Göttingen add an industrial and academic counterpoint to the state's historic core.

Destination Lower Saxony, Germany, Summary Lower Saxony's history spans the Saxon tribes who resisted Charlemagne's Frankish conquest, the Ottonian and Salian emperors who made Goslar an imperial seat funded by Rammelsberg silver, the Welf dynasty's rise under Henry the Lion at Brunswick, the Hanseatic salt wealth of Lüneburg, the 1648 Peace of Westphalia signed partly in Osnabrück, the personal union that placed Hanover's electors on the British throne from 1714 to 1837, Prussia's 1866 annexation of the Kingdom of Hanover, and the postwar founding of the modern state of Lower Saxony in 1946 by merging Hanover with Brunswick, Oldenburg, and Schaumburg-Lippe under British occupation administration.
