Museum History and Growth

The Natural History Museum opened in Exposition Park, Los Angeles, in 1913. It was first called The Museum of History, Science, and Art. A group of people who loved museums started it in 1910. The main building is very special. It has marble walls and a round, domed room. This building is even on the National Register of Historic Places. More parts of the museum were added in 1925, 1930, 1960, and 1976.
In 1961, the museum split into two parts. One part became The Los Angeles County Museum of History and Science. The other became the Los Angeles County Museum of Art (LACMA). LACMA moved to a new spot in 1965. Then, the Museum of History and Science changed its name. It became The Los Angeles County Museum of Natural History. Later, it changed its name one more time. Now, it is The Natural History Museum of Los Angeles County.
Modern Updates and New Exhibits
In 2003, the museum started a big project. They wanted to make their exhibits and visitor experience better. In 2010, the museum opened its main rotunda again. This old part of the building was made stronger. A new exhibit called "Age of Mammals" also opened. The exciting Dinosaur Hall opened in July 2011.
A new exhibit about Los Angeles history opened in 2013. It is called "Becoming Los Angeles." Also in 2013, the outdoor Nature Gardens opened. The Nature Lab also opened. These areas help visitors learn about wildlife in Los Angeles.
The museum plans to open a new part in 2024. It will be called the NHM Commons. This new area will be about 60,000 square feet. It will have new buildings and outdoor spaces. The Commons will be a community spot. It will have indoor and outdoor areas. These include a welcome area, a shop, a theater, a café, and a plaza.

The museum's collections are strong in many areas. But the mineralogy and Ice Age fossils are the most famous. This is because so many fossils come from The La Brea Tar Pits.

There have also been special exhibits about Los Angeles. One was called Becoming Los Angeles. It showed the city's history before and after 1929. Another exhibit is L.A. Underwater. It shows almost 40 fossils from a time when Los Angeles was under the sea.
The museum also has outdoor pavilions. A butterfly pavilion is open every spring and summer. A spider pavilion is on the same spot in the fall. Since 2017, the museum has had a special exhibit about P-22. This famous mountain lion lived in nearby Griffith Park.
Museum Architecture
Over the years, the museum has added new parts to its original building. The rotunda is one of the museum's most beautiful spaces. It opened when the museum first started in 1913. This room has marble columns and a stained glass dome. It is also home to the first public art paid for by Los Angeles County. This is a statue by Julia Bracken Wendt called Three Muses. It represents History, Science, and Art. This hall is very unique in Los Angeles. It has often been used as a place to film movies and TV shows.
