The lot of about is not an exclave, since it is not sovereign Czech territory. Nevertheless, it enjoys extraterritoriality and is therefore exempt from German legislation, and subject to Czech law. Previously, a similar arrangement existed for the port of Stettin, now Szczecin, Poland.
Even though Germany had already declared in advance that it would follow the decisions of the Commission, the lease was formalised in an agreement between Germany and Czechoslovakia, signed in Prague on 16 February 1929.
The lot was leased for 99 years. Until 2002, the Moldauhafen was used by the company ČSPL, which went bankrupt. The lease is set to expire in 2028.
