London Zoo reptile house

The London Zoo reptile house was the part of the London Zoo where reptiles were kept in London, England.

History
For Dudley Dursley's eleventh birthday on 23 June 1991, he, his family, and Harry Potter visited this part of the zoo. He was frustrated at the fact that the boa constrictor wouldn't move until Harry discovered he speaks Parseltongue, making the snake move. Dudley got excited when he saw the snake move so he pressed himself against the glass. Magically, the glass disappeared causing him to fall into the enclosure enabling the snake to escape. This caused chaos in the zoo, as people were running and screaming and the keeper of the Reptile House was watching in shock.
