The Lick Observatory is the official astronomical observatory of the University of California, located at the summit of Mount Hamilton within the Diablo Range near San José. As the first permanently-occupied mountaintop observatory in the world, the unique Classical Revival-style observatory was constructed in 1887 and is open to the public Thursdays through Sundays, though visitors should note that the observatory's access road can be a moderately strenuous drive and may not be accessible in all weather conditions. A free-admission visitor center showcases exhibits related to science and astronomy and also offers a public gift shop. Free public astronomy talks are offered throughout the day, allowing visitors to look through the observatory's 36-inch telescope dome.
