"How can we bring back the stars in our cities?" wondered Daan Roosegaarde. "Everyone should have the right to see the stars." This was the beginning of SEEING STARS.

SEEING STARS is our new collaboration with UNESCO and the city of Franeker, aiming to bring back the stars to your own street as our universal heritage.

Last night, Leiden became a remarkable experiment: SEEING STARS Leiden. Thousands of citizens turned off their lights around the Leiden Observatory. Despite the clouds, Saturn and other stars appeared over the historical streets. Walking through a darkened city with so many people felt like being an astronaut on Earth.” - Daan Roosegaarde

Exciting progress: A larger URBAN SUN, designed to cover a 3500m² area, is currently in development.

Inspired by science, Daan Roosegaarde’s URBAN SUN uses 222nm UV light—99.9% effective against coronavirus, as discovered by Columbia University, and safe for all. A beacon of urban innovation and hope.
