Brea (meaning "oil" or "tar" in Spanish) is a city in Orange County, California. The city began as a center of crude oil production and was later propelled by citrus production, and is now an important retail center because of the large Brea Mall and the recently redeveloped Brea Downtown. Brea is also known for its extensive public art program which began in 1975 and continues today with over 140 artworks in the collection placed and located throughout the city. Brea's public art program has been used as a model and inspiration for many public art programs across the United States. Brea was incorporated on February 23, 1917 as the eighth official city of Orange County.
