Harbours are for Swimming

Harbours are for Swimming

As a global port city, Rotterdam owes a big part of its identity to water. Yet much of the harbour landscape remains inaccessible to the city’s inhabitants, even now that the economic harbour activities have mostly moved westwards.

While the city is taking small steps to improve water quality and access, much work remains. That's why for this workshop we've teamed up with researcher and designer Martina Germanà to explore how the river Maas and its adjoining basins could once again become part of everyday urban life, not only as infrastructure, but as a shared public space for recreation, care, and collective imagination.

Structured as an intensive two-day workshop, the programme combines presentations, fieldwork, and design exploration. Participants are invited to bring their own references, personal swimming spots and inspiring initiatives as a starting point to build a shared vocabulary around urban swimming. Through lectures and discussions, the workshop situates Rotterdam within a broader international movement advocating for swimmable cities, drawing on historical precedents and contemporary practices.

A key component of the workshop is collective field research along the Maas. Participants will explore selected river stretches by foot or by bike, engaging in a form of citizen science guided by experts from Drinkable Rivers initiative (to be confirmed): observing spatial conditions, identifying potential access points, and testing water quality. These findings will be mapped and discussed collectively, building a shared spatial understanding of opportunities and constraints.

On the second day, will work individually or in groups, tol develop spatial interventions, communication strategies, or speculative scenarios for urban swimming: from physical design solutions to campaigns and manuals, aimed at making swimming in Rotterdam’s harbour waters imaginable and actionable.

The workshop concludes with a collective swim, embodying the central question of the programme: what would it take to reclaim the harbour as a space not only to look at, but to be able to engage with / access?
