For hundreds of years Antwerp has been one of Europe's key ports. Its history as a gateway for trade can be traced back as early as the 12th Century AD. Recently, its Port Authority grouped their technical and administrative services into one new headquarter location. Positioned on the docklands, the new facility consists of an existing heritage building and a newly formed extension. The existing structure is a protected replica of a Hanseatic House and former fire station. This heritage building required extending in order to house the 500 or so staff working across the Port Authority's various departments.
