Grič Tunnel: Zagreb’s Hidden Underground Passage

Tucked beneath the charming streets of Zagreb’s old town, the Grič Tunnel is a fascinating piece of history that has transformed into a unique attraction. Originally built in 1943 during World War II, this 350-meter-long tunnel served as a bomb shelter for civilians. After the war, it was largely forgotten until the 1990s, when it briefly became famous for hosting an illegal underground rave called "Under City Rave."

At the time, Zagreb was still recovering from the Croatian War of Independence, and the city was under blackout restrictions at night due to the conflict. Despite this, the abandoned tunnel became the site of one of the biggest and boldest underground parties in Croatia’s history. Thousands of young people, looking for a way to let off steam, packed into the tunnel, dancing to electronic beats under dim, flickering lights. 

The event was totally unauthorized, and when authorities found out, they shut it down. But by then, the Grič Tunnel had made headlines, and the once-forgotten passage was suddenly a symbol of resilience and rebellion. 

This unexpected moment in history helped put the tunnel back on the map, leading to its eventual restoration and reopening in 2016 as a cultural attraction!

 Today, visitors can walk through it for free and experience its cool underground atmosphere. 

 Some visitors hear whispers and feel sudden chills—echoes of history or something lurking in the shadows? 👻
