ISTRIADUCTION  June-Sempteber | Working time: 10.00 - 20.00h July, August: 10.00 - 22.00 | Pay per Entrance We visited the underground tunnel in the center of Pula, Zerostrasse. These amazing underground tunnels were made during the WW1 to provide a shelter for people in case of air raids. We saw the galleries and passages with the temperature during the whole year varies from 14 to 18°C. They told us that these tunnels, with their 3 to 6 meters wide and approximately 2.5 meters tall passageways, could accommodate about 6000 persons. Tips: Inside of the tunnels the floor was dirty because of the moisture and maybe you will get wet on your feet.
