Lick Observatory
The Lick Observatory is an astronomical observatory, owned and operated by the University of California. It is situated on the summit of Mount Hamilton, near San Jose, California, but is managed from the University of California, Santa Cruz, where its scientific staff moved to in the mid-1960s.

Lick Observatory was the world's first mountain-top observatory.
The observatory was constructed between 1876 and 1887, from a bequest from James Lick. In 1887 Lick's body was buried under the future site of the telescope, with a brass tablet bearing the inscription, "Here lies the body of James Lick."
Before construction could begin, a road to the site had to be built. All of the construction materials had to be brought to the site by horse and mule-drawn wagons, which could not negotiate a steep grade. To keep the grade below 6.5%, the road had to take a very winding and sinuous path, which the modern-day road still follows. Tradition maintains that this road has exactly 360 turns. (This is approximately correct, although uncertainty as to what should count as a turn makes precise verification impossible). Even those who do not normally suffer from motion-sickness find the road challenging.
The 91-cm refracting telescope on Mt. Hamilton was Earth's largest refracting telescope from when it saw first light on January 3, 1888, until the construction of Yerkes in 1897. In April, 1888, the observatory was turned over to the Regents of the University of California, and it became the first permanantly occupied mountain-top observatory in the world. The location provided excellent viewing performance due to lack of ambient light and pollution; additionally, the night air at the top of Mt. Hamilton is extremely calm, and the mountain peak is normally above the level of the fog that is often seen in the San Francisco Bay Area.
