Pyramids hold a kind of mysterious allure. Satisfy your kids' curiosity (and your own) when you pay a visit to the Walter Pyramid on the campus of California State University in Long Beach. This architectural attraction is hard to miss as its pyramid shaped structure creates a truly arresting image on the area's skyline. It is only one of three pyramid-shaped buildings in the country and is used for various functions on campus that include sporting events and conferences as well as weddings and even a backdrop for filming commercials and movies.
