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. It is 1,134 feet above sea level and is visible from many parts of the Los Angeles basin.

The Observatory is one of the most popular informal education facilities in the United States and the most-visited public observatory in the world (with over one million visitors a year). Griffith Observatory is a unique hybrid of public observatory, planetarium, and exhibition space. 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. Upon completion of construction in 1935, the Observatory was given to the City of Los Angeles with the provision that it be operated for the public with no admission charge. When it opened in 1935, it was one of the first institutions in the U.S. dedicated to public science and possessed the third planetarium in the U.S.

Since opening, the Observatory has welcomed over 76 million visitors. Open late nearly every evening, Griffith Observatory's audience is “the general public,” and it is one of the rare places where you will see people from every part of the region and from all parts of the world.

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. More people (7.5 million) have looked through the Observatory’s Zeiss 12-inch refracting telescope than through any other on Earth. More than 14 million have seen a live program in the Observatory’s Samuel Oschin Planetarium.
