It is also the town with the tallest and possibly most high rise buildings in the Netherlands. Numerous residential high-rise buildings are lined up in the very centre, all above 100 meters. Something quite unusual for Europe. On Dak van Rotterdam (the roof of Rotterdam) you can hope between the 360 views of the city from a whole range of the tall structures. one of the interesting tall structures currently under construction is the De Rotterdam designed by OMA.
And of course the main feature of Rotterdam is the international port handling a large percentage of all traffic in and out of Europe. This leads to a lot of traffic on the river Maas.
