Gotham Natural Science Museum

It is the building located directly north of the Mercy General Hospital.

Overview

Catwoman once broke into the museum and stole the Casanova Canary diamond but returned it soon after when she felt that the security protecting the diamond was not fitting for a diamond of its quality. Once the diamond was returned, security was increased and Catwoman stole the diamond again but returned it again for the same reason as before. Each time the diamond was returned, security was increased until Catwoman was satisfied that "her diamond" was adequately protected and in safe hands inside the museum.
