4.1 Mile Laser Rainbow Flag Returns to SF (June 23-25)

 The wondrous rainbow flag made up of massive laser space cannons will again flood San Francisco’s Market Street on Friday, June 23, 2023 and will continue for three nights, ending Sunday.

Called WELCOME (#WelcomeSF), the 4.1-mile installation by arts nonprofit Illuminate debuted last year to great fanfare, setting off celebrations up and down the length of Market Street.

With a 49-foot width and a length exceeding four miles, the installation will consist of six colored laser beams (purple, blue, green, yellow, orange, red) shooting horizontally above Market Street, rising at a subtle 3-degree angle to crest at Twin Peaks and represents the world’s largest pride flag.

This year, plans call for 12 laser space cannons, double the number of last year’s installation, creating an even more vibrant rainbow flag. A pre-lighting event is also planned from 7:00 – 9:00 pm at the base of the installation at Harry Bridges Plaza (near the Ferry Building). Speakers will include San Francisco Mayor London Breed, Illuminate CEO Ben Davis, and Speaker Emerita Nancy Pelosi. The lasers will be turned on at approximately 9:20pm.
