Natural History Museum of Los Angeles County
The Natural History Museum of Los Angeles County opened in Exposition Park, Los Angeles, California, United States in 1913 as the Museum of History, Science, and Art. The moving force behind it was a museum association founded in 1910. Its distinctive main building, with fitted marble walls and domed and colonnaded rotunda, is on the National Register of Historic Places. Additional wings opened in 1925, 1930, 1960, and 1976. The museum was divided in 1961 into the Los Angeles County Museum of History and Science and the Los Angeles County Museum of Art (LACMA). LACMA moved to new quarters on Wilshire Boulevard in 1965, and the Museum of History and Science was renamed the Los Angeles County Museum of Natural History. Eventually, the museum renamed itself again, becoming the Natural History Museum of Los Angeles County. In July 2010 the museum reopened its seismically retrofitted renovated 1913 Rotunda along with the new Age of Mammals exhibition. Its Dinosaur Hall opened in July 2011. Its history of California Under the Sun will open in late 2012. By that time the front of the building will be developed into 3.5 acres (14,000 m) of teaching-learning gardens as the new North Plaza.
