 Several historic homes dating from the late 1800s can be found as well, and their preservation is a key issue as development of the downtown area continues.North of downtown is the "Midtown" district along Main St., home to entertainment destinations such as the Bowers Museum, MainPlace Mall, and the Discovery Science Center.Near the intersection of the Santa Ana Freeway and the Costa Mesa Freeway is the newly designated "Metro East" area, which the city council has envisioned as a secondary mixed-use development district.
