9 cities in Lower Saxony are one of the most successful cities cooperations in Germany. Braunschweig, Celle, Göttingen, Goslar, Hameln, Hanover, Hildesheim and Wolfenbüttel jointly promote each other, especially abroad. The main targets of the activities of the marketing cooperation is to raise the awareness of the member cities and the increase of the number guests and overnight stays by marketing activities in neighboring European countries, but also within Germany.
Partners of the 9 cities alliance is the Autostadt in Wolfsburg, which addresses the same target groups, particularly in foreign markets. A visit to the Autostadt makes an attractive addition to a trip to the historic cities and vice versa. The Hannover Airport is the gateway to the 9 cities.
