Herman's tortoise - Ocellated lizard enclosre

You can see the bad planning here . Whoever designed this didnt know anything about tortoises, because they don't understand glass. I'm 99% sure they had to retrofit this nice naturalistic exhibit with that unsightly steel barrier after they wouldn't stop banging against it

In construction pictures of the zoo, found here: Paris, Vincennes zoo, France | Pangea Rocks you can see that these steel bars were in fact planned.

@Penshet Damn you did the research , fair enough guess im wrong. Strange design choice, but choice is was.
