Illuminate, the San Francisco nonprofit behind Leo Villareal’s The Bay Lights on the Bay Bridge, doesn’t build installations sized for a gallery — it builds them sized for a skyline. Its latest, 7X7, ran nightly from the summer solstice on June 21 through July 4, turning Civic Center Plaza into a field of 49 light beams climbing into the sky, one for every square mile of San Francisco’s famous seven-by-seven-mile footprint.

What made the concept work
The premise is almost embarrassingly simple once you hear it — 49 beams for 49 square miles — but that simplicity is exactly why it reads clearly at city scale in a way a more conceptually dense piece wouldn’t. The beams opened in rainbow color, then shifted to red, white, and blue ahead of Independence Day, tying the installation to both Pride season and the Fourth of July within the same run without needing to change the underlying structure of the piece. Visible across San Francisco and much of the Bay Area, it turned the nightly skyline itself into the display surface rather than confining the work to the plaza where the beams originated.
Why Illuminate keeps building at this scale
Illuminate reaches more than 20 million residents and visitors annually with work that’s deliberately always free and open to all — a mission that only makes sense at genuinely public, city-scale infrastructure rather than gallery or museum settings. 7X7 landed as San Francisco geared up for a stretch of major events, including Pride, the FIFA World Cup, and the country’s 250th anniversary, positioning the city for what organizers expect to be a record year for visitors. A free, sky-scale light installation timed to that moment functions as much as civic infrastructure as it does as art — which is precisely the register Illuminate has built its reputation working in since The Bay Lights first went up.
The throughline with The Bay Lights
7X7 isn’t a one-off experiment — it’s Illuminate applying the same free, monumental, always-on public art model that’s defined The Bay Lights for over a decade, this time aimed at the city’s own geography rather than a single piece of infrastructure. Both projects make the same bet: that public art scaled to an entire skyline, rather than a single site, changes how a city experiences itself at night, not just what visitors photograph.
