Background
Het Steen is a medieval fortress in the old city centre of Antwerp, Belgium, one of Europe's biggest ports. The surviving structure was built between 1200 and 1225 as a gateway to a larger castle of the Dukes of Brabant which was demolished in the 19th century. As the first stone fortification (city wall) of Antwerp, Het Steen is Antwerp's oldest building and used to be part of its oldest urban centre. The words "Het Steen", translated from Dutch mean "the rock" in English, although that is not the equivalent etymological meaning.
