CERN’s great outdoors

Inspired by urban design initiatives around the world, the “Outdoor Spots” project is transforming underused areas at CERN into perfect locations for picnics and walks

“Outdoor Spots” is transforming underused outdoor spaces at CERN into vibrant areas that promote soft mobility and a stronger sense of community. The project addresses challenges in navigating the Meyrin and Prévessin sites by linking key locations, creating a network of user-friendly pathways to encourage walking and biking.

View of IT Square
The IT square, between Buildings 513 and 31, includes five picnic tables connected by a footpath and surrounded by new and existing vegetation. A unique pedestrian pathway, resembling a distorted blue crosswalk, links the Data Centre to Building 31, facilitating movement between the entrances and the cafeteria, thereby encouraging outdoor circulation.

The project, launched last year as part of the Site Development Plan, is led by members of the SCE department in charge of landscaping and architectural integration. It draws inspiration from similar urban design initiatives around the world. Cities like Barcelona and Copenhagen have successfully revitalised asphalt-dominated areas by incorporating artistic and green elements. These interventions have not only beautified the spaces but also reduced car traffic without major construction work.

Outdoor Spots will share a common design language for easy recognition and maintenance. This includes consistent furniture, permeable ground surfaces, greenery and a coherent colour scheme. The elements will be adapted to each location’s specific context, ensuring both functionality and a sense of location.

Several Outdoor Spots already exist, such as the IT square, near the IT department’s buildings (Buildings 513 and 31); another near CERN’s kindergarten, which creates a pedestrian walkway that reduces traffic near Buildings 4 and 5; and one at Square Van Hove, the former Microcosm Garden, which has been beautifully reintegrated into the heart of CERN’s fenced campus, for the benefit of the entire CERN community. The redesigned spaces feature new lighting, greenery, clear signage and comfortable outdoor furniture – perfect for working, gathering or enjoying a picnic.

The Square Van Hove Outdoor Spot is also equipped with modern bike racks (with capacity for 40 bicycles) and two e-chargers to support CERN’s growing fleet of electric vehicles.

All Outdoor Spots are flagged as “Picnic areas” on MapCERN, making them easy to locate (Points of interest > Food & Drinks > Picnic area).
