The Moldauhafen is a 30,000 square metre area of the port of Hamburg that has been designated for the exclusive use of the Czechoslovak Republic for the movement of goods destined for that nation or goods being sent abroad by that nation. It was established in 1929 through an agreement between the German and Czechoslovak Governments by which the designated area was leased to Czechoslovakia pursuant to the Treaty of Versailles which provided:
Article 363 - In the ports of Hamburg and Stettin Germany shall lease to the Czechoslovak State, for a period of 99 years, areas which shall be placed under the general regime of free zones and shall be used for the direct transit of goods coming from or going to that State.
Article 364 - The delimitation of these areas, and their equipment, their exploitation, and in general all conditions for their utilisation, including the amount of the rental, shall be decided by a Commission consisting of one delegate of Germany, one delegate of the Czechoslovak State and one delegate of Great Britain. These conditions shall be susceptible of revision every ten years in the same manner. Germany declares in advance that she will adhere to the decisions so taken.
The port facilities in question allow the unimpeded flow of goods to and from Czechoslovakia via the Moldau, Elbe and Oder rivers. A similar facility exists in the port of Stettin.
