Where are the Watts Towers, a collection of 17 interconnected sculptural towers, located?

Watts gave it away.

I've seen grottos with a similar broken glasses and tiles. decorated walls and many other things in different countries. folk art?

I remember my dad taking us on a day trip to see them.

Deb I saw it on a school field trip. Thought it was really cool even ṭhroigh a child's opinion

I think there was a police chase down there in the movie Colors.
