Lick Observatory

Lick Observatory was founded in 1888 using a bequest from James Lick, a wealthy San Francisco real estate magnate who died in 1876. Lick left approximately $700,000 for the project, which was the largest private donation for scientific research at the time. James Lick himself is buried beneath the telescope pier of the Great Lick Refractor at the observatory.

The largest telescope at Lick Observatory is the Shane 3-meter (120-inch) reflecting telescope, which has been in operation since 1959. The observatory also houses the 36-inch Great Lick Refractor, which was the largest refracting telescope in the world when it was completed in 1888. The facility is operated by the University of California and continues to conduct active astronomical research.

Lick Observatory is located on the summit of Mount Hamilton in the Diablo Range east of San Jose, California, at an elevation of approximately 1,280 meters. Access is via Mount Hamilton Road (Highway 130), a winding road with over 300 curves that was originally built in the 1870s to transport telescope components. The road remains the only vehicular access route.

Yes, Lick Observatory is open to visitors during scheduled public programs, typically offered on weekends during summer months. Visitors can take guided tours of historic telescopes including the Great Lick Refractor and attend evening programs with telescope viewing when weather permits. The observatory also hosts a summer concert series and special events.
