The museum is located on what was the county agricultural fairgrounds. By the 1890s it had become a place for gambling, saloons, dog and rabbit racing, and other vices. Sunday school preacher William Bowen, seeing the immoral state of the grounds, spearheaded the effort to establish a cultural institution beginning in the late 1890s. After a decade of effort, the land was finally designated to be the site of a new museum.The building was designed by Frank Hudson and William Munsell and they incorporated Beaux Arts, Romanesque, and Spanish Revival elements. In 1963, the art department moved to another building that would become the Los Angeles County Museum of Art. The museum then became simply the Museum of History and Science, but the name was eventually changed to its current one. The last major renovation occurred in 2009.
