"Butantan (Serpentario), S. Paulo."

A real photo postcard of the serpentarium (serpentário) at the Butantan Institute (Instituto Butantan) in São Paulo, Brazil.

The mound-like concrete structures house the snakes, and the wall that encloses the area keeps visitors safe while they observe them. The Butantan Institute is a major research center with an extensive collection of venomous snakes that are used in the manufacture of antivenom.
