Situated behind the law courts at the Citadel of Victoria, Gozo, the Natural Science Museum is situated in an old house, the origins of which may date back to the Aragonese period. The geology on exhibits includes marine organisms deposited on the sea floor between 35 and 5 million years ago, as well as fragments of fossil bones from Ice Age elephants and hippopotami. The centrepiece is a selection of stalactites and stalagmites from Gozitan caves. Two other sections on this floor are dedicated to human and animal evolution as well as marine life.
The second floor exhibits an ornithology display; a small collection of stuffed and mounted birds, the majority of which are migratory and most of which are now legally protected species. The entomology room holds a small but impressive collection of exotic insects, butterflies and moths. The last display is dedicated to the flora and ecosystems of the Maltese Islands, particularly of Gozo.
