Antwerp (officially called Antwerpen in Dutch) is an Earth city in the northwestern part of Belgium, close to the Dutch border, capital of the homonymous local province.
In 2372, Antwerp was the location of a high level diplomatic conference held between the Federation and Romulan Empire. It was bombed by a Changeling infiltrator, killing 27 people, including the Tholian observer. The attack signified a Dominion presence on Earth. (DS9: "Homefront")
- It is unclear whether or not Antwerp hosts a specific Federation office, such as Paris, San Francisco and Lisbon do.
