Fort Moore was an historic U.S. Military Fort in Los Angeles, California, during the Mexican–American War. Its approximate location was at what is now the Hollywood Freeway near the intersection of North Hill Street and West Cesar Chavez Avenue, downtown. The hill on which it was built became known as Fort Moore Hill, most of which was removed in 1949 for construction of the freeway. The hill was located one block north of Temple Street and a short distance south of present day Cesar Chavez Avenue, between the Los Angeles Civic Center and Chinatown. A small portion of the hill was not bulldozed and remains on the west side of Hill Street on the north side of the freeway. The fort is now memorialized by the Fort Moore Pioneer Memorial.
Part of Fort Moore Hill became home to a cemetery, with the first documented burial tracing back to December 19, 1853. Alternately known as Los Angeles City Cemetery, Protestant Cemetery, Fort Moore Hill Cemetery, Fort Hill Cemetery, or simply "the cemetery on the hill", it was the city's first non-Catholic cemetery.
The cemetery was overseen by the city starting in 1869. It was not well taken care of, lacking clearly delineated boundaries, complete records or adequate maintenance. The Los Angeles City Council passed a resolution on August 30, 1879, closing the cemetery to any future burials except for those with already reserved plots. By 1884, the city had sold portions of the cemetery as residential lots and the rest to the Los Angeles Board of Education (later the Los Angeles Unified School District.
The city never removed any bodies, and the former cemetery was the site of repeated, grisly findings and much negative press. As a result, the city began moving the bodies, most to Evergreen Cemetery, Rosedale Cemetery and Hollywood Memorial Park Cemetery, with the final bodies being transferred in May 1947. The recent construction of Los Angeles High School #9 resulted in the discovery of additional human remains. These were excavated by archaeologists in 2006.
