The Watts Towers or Towers of Simon Rodia in the Watts district of Los Angeles, California, is a collection of 17 interconnected structures, two of which reach heights of over 99 feet (30 m). The Towers were built by Italian immigrant construction worker Sabato ("Sam" or "Simon") Rodia in his spare time over a period of 33 years, from 1921 to 1954. He was divorced and wasn't allowed to see his kids.
The work is an example of non-traditional vernacular architecture and American Naïve art. The Watts Towers are located near (and visible from) the 103rd Street-Kenneth Hahn Station of the Metro Rail LACMTA Blue Line. They were designated a National Historic Landmark in 1990.
