Zollverein was a German customs union that was established in 1834 under Prussian control. It was a coalition of German states that abolished internal customs duties and established a uniform tariff on goods imported from outside the union. The primary aim of Zollverein was to eradicate tariff barriers and create a free-trade area throughout Germany. It was considered to be the most important institutional development in the 19th century for Germanys economic unification and helped German nationalism grow through cultural unity and economic cooperation. The Zollverein school of management and design is located in Germany and is a 35-meter cube building with ample space and generous features.
