Havenhuis
One relatively recent addition to the dynamic Antwerp skyline is the Port House, home of Antwerp's Port Authority. Located at the northern end of Het Eilandje, the shiny diamond-shape lozenge on stilts actually rests on top of a beautifully restored old fire station. It was designed by renowned architect Dame Zaha Hadid, and completed shortly before her death in 2016. You can only visit the neo-futurist construction by arranging a group tour (Tuesday, Thursday, and the first Saturday of each month only), which costs a hefty €150 per group, but its stunning exterior appearance has made it a noteworthy showstopper even if you don't go in.
