Griffith Observatory is an icon of Los Angeles, a national leader in public astronomy, a beloved civic gathering place, and one of southern California’s most popular attractions. The Observatory is located on the southern slope of Mount Hollywood in Griffith Park, just above the Los Feliz neighborhood. he Observatory is one of the most popular informal education facilities in the United States and the most-visited public observatory in the world (with 1.5 million visitors a year). It was constructed with funds from the bequest of Griffith J. Griffith (who donated the land for Griffith Park in 1896), who specified the purpose, features, and location of the building in his 1919 will. Fulfilling the Observatory’s goal of “visitor as observer,” free public telescope viewing is available each evening skies are clear and the building is open. As early as 1978, public and private officials recognized that the Observatory’s future would depend on a concerted effort to restore the existing building and expand it to improve the experience for the vast audiences who visited each year. Guided by a 1990 Master Plan, the City of Los Angeles non-profit Friends Of The Observatory crafted a unique public-private partnership to renew the Observatory for generations to come. The building closed to the public on January 6, 2002, to begin this work. A world-class team of architects, exhibit designers, astronomy experts, construction workers, exhibit fabricators, instrument and equipment builders, and many others worked carefully and expertly for four years to return Griffith Observatory to the people of Los Angeles and beyond.
