The Rotterdamse Dakendagen (Rotterdam Rooftop Days) are a festive exploration of the rooftops of Rotterdam.

Rotterdamse Dakendagen aims to show how rooftops could contribute to healthy, lively, inclusive, sustainable, attractive and resilient cities. We do this by organising our annual festival the Rotterdam Rooftop Days, where thousands of residents and visitors of the city are welcomed to explore its currently underutilised rooftops, collectively known as the roofscape.
