Workman and Temple Family Homestead Museum, Historic house museum in City of Industry, California, USA

The Workman and Temple Family Homestead Museum at 15415 East Don Julian Road in the City of Industry holds two family houses and the private El Campo Santo cemetery. The Workman House is a two-story adobe with brick wings added around 1870, eight rooms on the first floor and three finished upstairs. La Casa Nueva, built 1922–1927 in Spanish Colonial Revival style, has twenty-six rooms and adobe bricks made by artisans under Pablo Urzua.

William Workman, born in England in 1799, reached the San Gabriel Valley in 1841 and built an adobe house in 1842 on part of Rancho La Puente. By 1870 the house had been enlarged with brick wings and a second story, a remodeling attributed without documentation to architect Ezra F. Kysor. The family lost the property in 1900 after its bank failed in 1876.

The name honors two families whose lives shaped the property across generations. Visitors can see how rooms are furnished with period objects and personal items that reflect the daily lives and choices of those who lived there.

Visitors should plan to participate in guided tours, as access to the interiors of the houses is available only this way. It helps to wear comfortable shoes since the tour leads through various rooms and across the grounds.

El Campo Santo was established in the 1850s; the earliest documented burial is David Workman's, in November 1855. In 1857 Bishop Thaddeus Amat blessed the cornerstone of St. Nicholas's Chapel, named for William Workman's wife, Nicolasa Urioste de Valencia. The Gothic Revival chapel, 24 by 48 feet with gilt ceilings and stained glass, was later said to have burned and was razed.
