Rotterdam has a new slogan: 'Make it happen'. This should put the city of Rotterdam on the international map. The new slogan was unveiled on Monday, December 15, 2014 by Mayor Ahmed Aboutaleb, director Allard Castelein of the Port Authority, chairman of the board Pauline van der Meer Mohr of Erasmus University and director Ros Voskuilen of Rotterdam Partners, the organization that promotes the port city's economy. It is the first time that the municipality, the university and the port company will be sharing the same slogan. The official cooperation has been confirmed by the parties involved by placing the signatures on our graffiti wall.
