From Wikipedia: Chicano Park is a 32,000 square meter (7.9 acre) park located beneath the San Diego-Coronado Bridge in Logan Heights (Barrio Logan), a predominantly Mexican American and Mexican-immigrant community in central San Diego, California. The park is home to the world’s largest conglomeration of outdoor murals (67), as well as various sculptures, earthworks, and an architectural piece dedicated to the cultural heritage of the community.
