Tustin is a small suburban town which lies between Santa Ana and Irvine. The original town was established by orange grower Columbus Tustin in the early 1900s, along a stretch of El Camino Real, as an agrarian trading post. The town remained largely rural until World War 2, when the military built a large Air Force base on the city's eastern border. The city, which grew up around the base following WWII, continued to feel a strong military identity until the base was finally shut down in 1997. Today, the main attraction is The Market Place, a sprawling shopping district begun in 1988, which has since expanded to cover four city blocks in two cities.
