museum complex with distinguished collections of Asian (Indian, Tibetan, Nepalese), Islamic, medieval, European, and modern art. At the beginning of the 21st century, the LACMA held more than 100,000 works of art. The largest building, the four-level Ahmanson Gallery, houses the permanent collection, the adjoining Frances and Armand Hammer Wing displays temporary exhibitions, and the Leo S. Bing Center contains a library (with more than 60,000 volumes) and auditorium. The Robert O. Anderson Building, housing the museum's modern-art collection, opened in 1986. The Textile and Costumes Research Center is the strongest in the western United States. Established in 1910, the museum was part of the Los Angeles County Museum of History, Science and Art until 1961, when it became an independent institution. It moved to its present location in 1965.
