In this old arsenal from 1823, you will be plunged in the world of the sea: a naval review where you can see a parade of famous old ships, a pirates den, the shipwreck of the Titanic, the treasure island of Captain Leborgne... From the 64m high crow's nest, there is an attractive view over Zeeland, Belgium and west Escaut. The visit finishes with a visit to the underwater world (aquariums, a sperm whale skeleton).
