Moldauhafen

Moldauhafen (Vltava port) is a lot in the port of Hamburg, Germany, that Czechoslovakia acquired on a 99-year lease in 1929 pursuant to the Treaty of Versailles. In 1993, the Czech Republic succeeded to the rights of Czechoslovakia,. The lease will expire in 2028.

The lot is not an exclave as it is not sovereign Czech territory. Previously, a similar arrangement existed for the port of Stettin, now Szczecin, Poland.

The lot is one of three lots that the Czech Republic has rights over. The other two are Saalehafen and Peutehafen. Saalehafen comes under the Versailles Treaty but then-Czechoslovakia purchased Peutehafen in 1929. Both Moldauhafen and Saalehafen are part of the Hamburg free port, and sit on the embankment of Dresdner Ufer and Hallesches Ufer. The area comprises about 28,500 square metres (306,771 sq ft). The leased premises constitute a duty-free zone that were called the Czecho-Slovak rental zone for inland navigation in the free port of Hamburg.

Peutehafen comprises an area of about 13,500 square metres (145,313 sq ft). It lies on the narrow peninsula between the Peutekanal and the Peutehafen dock, and is just outside the Hamburg free port.

In 2004, the city of Hamburg expressed interest in acquiring the two leased areas, as its proposed plan for hosting the 2024 Summer Olympics would have blocked access to Moldauhafen. The city also desired to develop the two areas. The city offered the Czech Republic a new site in exchange, with the inducement of a better location. For its part, the Czech Republic wished to continue to use its ports in Hamburg even after the expiration of the 99-year leases.

The 1919 Treaty of Versailles stated in articles 363 and 364:

In the ports of Hamburg and Stettin Germany shall lease to the Czecho-Slovak 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.
