Griffith Observatory

Griffith Observatory is an observatory in Los Angeles, California, on the south-facing slope of Mount Hollywood in Griffith Park. It commands a view of the Los Angeles Basin including Downtown Los Angeles to the southeast, Hollywood to the south, and the Pacific Ocean to the southwest. The observatory is a popular tourist attraction with a close view of the Hollywood Sign and an extensive array of space and science-related displays. Named after its benefactor, Griffith J. Griffith, admission has been free since the observatory's opening in 1935, in accordance with his will. Since its opening, over 9 million people have looked through the 12-inch (30.5 cm) Zeiss refracting scope, making it the most viewed telescope in the world. The space theme prevails in the interior.
