If you are interested in learning about the flora and fauna of the Karst caves, don't miss the opportunity to visit the Speleovivarium.

The only museum of its kind, the Speleovivarium is located in the heart of Trieste, in a tunnel that is a former air raid shelter. The unusual location was chosen for its physical and environmental characteristics, similar to those of natural Karst caves. 

In this space, the Adriatic Speleological Society has set up a museum tour primarily aimed at underground world.

Educational workshops are held to understand how life develops in darkness and how environmental and climatic pollution also affects underground environments; additionally, there are installations dedicated to biology, geology, karstology, the history of speleology, and water research.

There is also a screening room, an area dedicated to temporary exhibitions, and a section dedicated to Urban Speleology.
