Below Pula is an underground tunnel world stretching almost across entire Pula, known as Zerostrasse. Pula's underground tunnels were erected during the WW1 to provide a shelter for people in case of air raids.
The underground tunnel system consisted of shelters, trenches, galleries and passages, as well as ammunition storages and communication passages. Each hill in the town's core was drilled and dug up, thus creating an extended tunnel network. The tunnels of Monte Zaro, Monte Ghiro and the Castel are the largest.
