A popular intersection in San Francisco’s Haight District is now an official “national treasure”. The National Trust For Historic Preservation is declaring the corner of Haight and Ashbury a national treasure, which means the nearby Doolan-Larson building will be preserved as part of history. The 109-year-old building was home to one of the first hippie clothing shops run by late singer Janis Joplin’s lover. It’s where legendary guitarist Jimi Hendrix got his signature bell-bottoms and vest. The declaration also recognizes Haight and Ashbury as the birthplace of the Summer of Love movement.
