Location: 1686 East 103rd St., Los Angeles
Significance: Only building left standing after the Watts Riots
In response to the arrest of Marquette Frye, his brother, Ronald, and their mother by California Highway Patrol motorcycle officer Lee Minkus on August 11, 1965, the neighborhood of Watts became a war zone for the next five days. 34 people were killed, over 1,000 were injured, more than 3,000 were arrested. Los Angeles was left with an estimated $40 million in property damage. The Watts Riots were the most severe in the city until 1992, with most of the damage happening on 103rd Street, which became known as "Charcoal Alley" because nearly everything was burned to the ground. In the midst of the destruction, one building remained: Watts Station. Nobody is sure if the train station was left intact on purpose or by coincidence, but it became a symbol of hope in the aftermath of the riots. Four months after they ravaged the city, Watts Station was named a Historic-Cultural Monument. It was added to the Register of National Historic Places in 1974.
