The last two caves used by the Austro-Hungarian army included in the open-air Museum of Mt. Ermada are Karl and Zita Caves, also known as Gavetta Cave and Pilone Cave. Their names, assigned by the Habsburg Imperial Command, were chosen in honour of the new Emperor, Karl I, who succeeded Franz Joseph, and his wife, Zita of Bourbon.
They both feature several levels connected by stairs, where soldiers could rest or find temporary shelter from enemy fire. The recent cleaning of the entrance stairs leading to Karl Cave allows visiting its interior. In addition, thanks to the work carried out by a team of archaeologists, it is now possible to walk from Karl to Zita Cave through a narrow tunnel, which had initially been excavated by soldiers but was never completed.
