Zerostrasse, Underground tunnel complex and museum in Pula, Croatia.
Zerostrasse consists of a network of underground tunnels extending approximately 400 meters beneath Kaštel Hill, featuring corridors with widths between three to six meters and heights around 2.5 meters that could accommodate up to 6,000 people.
The tunnels were constructed during World War I under the Austro-Hungarian Empire to serve as bomb shelters and protective passages, later functioning as military quarters, storage areas, and prisons during various periods of conflict throughout the 20th century.
The site represents Pula's wartime resilience and strategic urban development, now serving as a museum that preserves military history through exhibits, artifacts from the early 20th century, and multimedia displays that engage visitors with the city's heritage.
The museum operates daily from 09:00 to 21:00 during peak season and until 17:00 from October to March, offering wheelchair accessibility and guided tours that provide detailed insights into the tunnels' construction and historical significance.
The tunnels maintain constant temperatures between 14 and 18 degrees Celsius year-round and have been adapted for modern cultural events including art installations and concerts, blending historical preservation with contemporary cultural programming.
