Los Angeles Historic-Cultural Monument

Los Angeles Historic-Cultural Monuments are sites which have been designated by the Los Angeles, California, Cultural Heritage Commission as worthy of preservation based on architectural, historic and cultural criteria.

The Historic-Cultural Monument process has its origin in the Historic Buildings Committee formed in 1958 by the Los Angeles chapter of the American Institute of Architects.

As growth and development in Los Angeles threatened the city's historic landmarks, the committee sought to implement a formal preservation program in cooperation with local civic, cultural and business organizations and municipal leaders.

The original Cultural Heritage Board (later renamed a commission) was formed in the summer of 1962, consisting of William Woollett, FAIA, Bonnie H. Riedel, Carl S. Dentzel, Senaida Sullivan and Edith Gibbs Vaughan.

In its first day of official business, the board designated the Leonis Adobe and four other sites as Historic-Cultural Monuments.
