"Since the regeneration of the area in the 30s, the main plaza on Olvera Street has hosted a vibrant Mexican marketplace. It's home to some of the city's oldest and most historic buildings (26 of them) including the Avila Adobe, built in 1818, LA's oldest surviving residence; Pico House, a luxury hotel built in 1870; and the Plaza Substation that used to form a part of the Yellow Car network."
