El Campo Santo Cemetery, Historical cemetery in City of Industry, United States.

El Campo Santo is a one-half acre cemetery enclosed by low brick walls at the Workman and Temple Family Homestead Museum in City of Industry. It holds a Neoclassical cast stone mausoleum and a small burial plot surrounded by a Gothic Revival cast-iron fence.

William Workman established this private burial ground in the 1850s on his family estate, which later became the resting place for prominent California settlers and local families. The site evolved throughout the 1800s and received its neoclassical mausoleum in 1917.

The cemetery's name is Spanish for "the sacred ground," chosen by the Workman family in the early 1850s. A Gothic Revival brick chapel dedicated to Saint Nicholas by Bishop Thaddeus Amat once stood here; it burned down around 1900. The first burial was William Workman's brother David, killed in 1855 while driving cattle to the gold fields.

Visitors can explore the grounds during daylight hours on self-guided tours, with information available at the museum office located on the property. The cemetery is accessible from Don Julian Road and most areas are easy to walk through.

Pío Pico, the last governor of Alta California, and his wife Ygnacia Alvarado de Pico were moved here in 1921 from old Calvary Cemetery in Downtown Los Angeles, which was being relocated. Their remains lie in the cast stone Neoclassical mausoleum Walter P. Temple built in place of the burned brick chapel.
