As San Francisco gears up to celebrate the golden anniversary of the Summer of Love—where, in 1967, an estimated 100,000 youths, sporting flowers in their hair and LSD on their brains, converged in the Haight-Ashbury sparking the hippie social movement—scores of city structures and buildings will pay tribute to that patchouli-laced era. One venue’s celebration promises to be especially noteworthy. The landmark Conservatory of Flower building in Golden Gate Park will light up in a myriad of colors. Illuminate, the group behind the Bay Lights, and Obscura Digital, a creative studio focusing on light-based art, will transform the stark white landmark with a series of illuminated scenes, which according to the conservatory, are “inspired by the rare tropical flowers within and the legacy of San Francisco’s flower children.” Ben Davis, Director of Illuminate, said in a press release, “We are bringing that light back to where it all began in Golden Gate Park fifty years later with an electrifying, contemporary tribute.” Groovy. Light show can be seen nightly from sundown until midnight from June 21 through October 21.
