This photo is one in a series taken during a recent trip to the Watts Towers, located in Watts (a region of Los Angeles, famous for the riots in the 1960s). The towers are magnificent- doubly so as they were hand crafted by one man.
The Watts Towers, Towers of Simon Rodia, or Nuestro Pueblo (“our town”) are a collection of 17 interconnected sculptural structures within the Simon Rodia State Historic Park in the Watts community of Los Angeles. The tallest of the towers reaches a height of over 99 feet (30 m). The towers and walls were designed and built by Sabato (“Simon”) Rodia (1879-1965), an Italian immigrant construction worker and tile mason, over a period of 33 years, from 1921 to 1954. The work is an example of outsider art and Italian-American naïve art.
The Watts Towers are located near the 103rd Street/Watts Towers Los Angeles Metro station of the Los Angeles County Metro Rail Blue Line, and off the I-105 Century Freeway. They were designated a National Historic Landmark and a California Historical Landmark in 1990. They are also a Los Angeles Historic-Cultural Monument, and on the National Register of Historic Places in Los Angeles.
