You still have until 24 June to visit the Rotterdam Rooftop Walk . Designed by MVRDV it was created to draw attention to the challenges the second largest Dutch city faces because of the #climatechange and rising sea level.

Companies and NGOs show their latest rooftop innovations in green roofs, #energytransition, #water retention, rooftops as public space and more. Together with contributions from the arts and sciences, these form a manifestation of innovative rooftop use and a vision of a possible #future for cities utilising their roofscape to the fullest.
