Olvera Street, commonly referred to as the "Birthplace of Los Angeles" is a Mexican marketplace with a look and feel that recreates the old L.A. Originally an alley jutting off the Plaza, the street is narrow, brick lined amid shady trees, old buildings housing cafes, restaurants, and gift shops. Olvera Street was conceived in 1930 to preserve and present the customs and trades of the original Californios. Many of the Plaza District's Historic Buildings are on Olvera Street, including the Avila Adobe (1818), the Pelanconi House (1857), and the Sepulveda House (1887). In 1926, as the modern Los Angeles took hold, a preservation effort by Christine Sterline and Harry Chandler saved the buildings from demolition and established the tiny thoroughfare as a Mexican marketplace.
