• Centro — This is the historical midpoint of Tijuana; the municipal palace is located here as well as most of the tourist zones, such as Avenida Revolución and the business district. The Tijuana Cultural Center (CECUT for CEntro CUltural de Tijuana) is located here as well as the Plaza Río Tijuana, until recently the largest mall in the state.
