What is a Superblock

Superblocks, known as "Superilles" in the Catalan language, embody Barcelona's innovative approach to reshaping its urban environment. This design concept restructures street clusters, giving priority to people on foot, bike riders, and community spaces—all while curbing car traffic. Each superblock is larger than a single block, but not as extensive as an entire neighborhood, typically spanning 400 x 400 meters.

At the heart of a superblock, inner streets become havens for pedestrians, closed to passing vehicles. The surrounding perimeter streets continue to welcome car traffic. Within the superblock's bounds, vehicles access only for specific purposes—residential entry, public transit, aiding those with disabilities, emergencies, and leisurely biking. Cars travel one-way and adhere to a 10 km/hour speed cap.

These changes unlock a world of possibilities—playgrounds, greenery, seating, and communal areas. Here, social bonds flourish, and neighborhoods come to life. Superblocks champion community, sustainable transit, and harmony with nature by taming traffic, nurturing plant life, and embracing inclusivity.

People first, cars second—this guiding ethos shines through in the superblock initiative. Accessibility, ease of walking, and eco-friendly travel are paramount. The voices of residents and businesses shape the journey, their insights steering the planning stages.

The Urban Mobility Plan of Barcelona 2013-2018 lit the spark for the superblock movement, envisioning a citywide network of 503 superblocks. The blueprint includes pedestrian-only zones, biking paths, and seamless public transit.

Despite facing hurdles—shopkeepers' objections and gentrification fears—superblocks stand out as a beacon of urban planning excellence. They promise a future where cities breathe, communities thrive, and every resident belongs.
