"Simon Rodia [an Italian immigrant] 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." (Source)
"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." (Source)
"They are decorated with found objects, including bed frames, bottles, ceramic tiles, scrap metal and sea shells. [Rodia] built them with no special equipment or predetermined design, working alone with hand tools and window-washer's equipment. Neighborhood children brought pieces of broken glass and pottery to Rodia, some of which were added, but the majority of his material consisted of damaged pieces from the Malibu Pottery or CALCO (California Clay Products Company), located nearby. Green glass includes recognizable soft drink bottles from the 1930s through 1950s, some still bearing the former logos of 7 Up, Squirt, Bubble Up, and Canada Dry; blue glass appears to be from milk of magnesia bottles."

I really had no idea what to expect here, but I'm so glad we stopped by and got to experience first hand this fascinating historic American folk art.
