115 - Xilitla, Mexico

In San Luis Potosí state, near the Veracruz border.

Just outside town there's a concrete surrealist landscape, Las Pozas, built in the 1960s by the Englishman Edward James, a sort of Watts Towers in the jungle. Though in Mexico there's so much more of a rich context for amazing undulating massive structures, tombs, and pyramids.
