Corona CA’s most prominent feature, and the one that gave it its name in 1896, is the circular Grand Boulevard that runs around the center of the city, circling the downtown like a crown or corona in Spanish. For many years, Corona CA was known as an agricultural area, producing mainly citrus fruits as well as some dairy. However, by the 1990s more development had occurred and the city became more suburban and industrial. In fact, it is now sometimes called the Gateway to the Inland Empire, a region known for its busy shipping and logistics industries.
