The Watts Towers are a complex set of 17 separate sculptural pieces built on a residential lot in the community of Watts. Two of the towers rise to a height of nearly 100 feet. The sculptures are constructed from steel pipes and rods, wrapped with wire mesh; coated with mortar; and embedded with pieces of porcelain, tile, and glass. Using simple hand tools and cast off materials (broken glass, sea shells, generic pottery, and ceramic tile) Italian immigrant Simon Rodia spent 30 years (1921 to 1955) building a tribute to his adopted country and a monument to the spirit of individuals who make their dreams tangible. The Watts Towers are one of only nine works of folk art listed on the National Register of Historic Places. The site is one of only four US National Historic Landmarks in the city of Los Angeles. The Los Angeles City Cultural Affairs Department, through the Watts Towers Arts Center, provides diverse cultural enrichment programming through tours, lectures, changing exhibits, and studio workshops for both teachers and schoolchildren. Each year, thousands of people are attracted to the Towers' site for the Simon Rodia Watts Towers Jazz Festival and the Watt Towers Day of the Drum Festival.

The park offers exhibits, tours, lectures, workshops, and educational and recreational events.
