The first show in the app is ‘Hier zijn de Van Rossems’, in which the Van Rossem family of scientists guides you through cities. They will walk you along locations and objects, and tell their stories about them. Maarten tells all about history, Sis about Art and Vincent is an expert on architecture. Using the NTR app, you’ll be able to walk the tours yourself. The app contains video’s that aren’t showed in the show, and extra information about the objects and the locations. The cities in the app and the program are Maastricht, Rotterdan, Brugge, Naarden, Dordrecht and Essen.
