Opened in 1926, the Witte Museum interprets the history, culture and natural science of the region. Elaborate dioramas and exhibits explore native species, dinosaur life and the canyon rock art of prehistoric and historic Native Americans. The site also preserves a Spanish colonial home, Mexican-era residence and 1915 studio of artist Julian Onderdonk. The newly opened South Texas Heritage Center, located in the adjacent 1936 Centennial Pioneer Hall, is a place where the stories of 1850s South Texas come to life through interactive exhibits, art, artifacts and live performances.
