The capital city of Germany’s northern state of Lower Saxony, Hannover was founded on the banks of the River Leine in Medieval times. The red brick of the Altstadt remains prominent, despite sustaining damage during the Second World War, and many iconic buildings stand again after being immaculately restored. Hire a car from Hannover-Langenhagen Airport and visit Hannover’s 17th century Herrenhäuser Gärten. This expansive array of beautifully tended gardens is home to such exquisite spaces as the Grosser Garten, the Welfengartem and the Berggarten.
