Swimmable Cities is an alliance of 153 signatory organizations across 59 cities in 22 countries, supporting the global movement for swimmable urban waterways. In the context of increasing urbanization, climate change, and biodiversity loss, the initiative aims to reclaim rivers and harbors as public spaces for communities to enjoy and benefit from bathing. It advocates for urban waterways to be made safe, healthy, and accessible for both swimmers and wildlife, calling for cross-border collaboration to develop improvement strategies and collect data to evaluate "swimmability." This call becomes especially relevant amid rising global temperatures and growing inequalities in access to public infrastructure in major cities. The movement's 10-point charter begins with the affirmation of "the right to swim," celebrating urban swimming culture and recognizing the historical significance of water.

Public spaces are the beating heart of our cities. They act as the hubs of social and cultural activity where people congregate, interact, and escape the clamor of the city. These areas are crucial in determining a city's identity, character, and citizens' well-being and standard of living. Public spaces can define our communities and significantly impact how we live, work, and interact with one another through their architectural designs, facilities, and activities. Furthermore, they provide leisure, exercise, and recreation opportunities, allowing individuals to escape the confines of their daily routines and connect with nature.
This week's curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community showcasing different proposals made to enhance public space. Ranging from reimagining central squares to placing massive land art in the urban epicenter, these public spaces enhance the quality of life for the city's locals. In Germany, the redesign of the entire Memorium Nürnberger Trials reimagines this as a place to come together, grounded in its history, while in Havana, the new Cuban Square reimagines the metaphor of unity in the city center. The design and accessibility of public spaces significantly impact our well-being and quality of life. Thoughtfully planned and inclusive spaces with seating, greenery, and pedestrian-friendly infrastructure can promote physical activity, mental health, and community engagement in a city.
