The MAS museum, designed by Neutelings Riedijk Architects, is one of the eye-catchers of the Antwerp skyline. It is located in the old part of the port in the quarter called ‘t Eilandje (the little island), which in the past decade has spectacularly transformed from a rundown neighbourhood to a trendy and posh place. MAS stands for Museum aan de Stroom, Dutch for the museum by the river (Scheldt). It houses several exhibits, ranging from maritime objects illustrating the history of the port to one of the most interesting pre-Columbian collections of Belgium. And there’s more: you can climb the rooftop for free to enjoy an amazing 360° panorama over the city and its port! While the museum closes at 5 pm already, the rooftop is accessible until 10 pm.
You can get to the MAS with tramline 7 or just have a nice 1 km walk from the Groenplaats via Lange Koepoortstraat and Klapdorp.

If you have time left, you can have a quick look at the Felixpakhuis, a well-preserved warehouse now housing the city archives at Godefriduskaai 30.
