Open to the public in 2016, the Grič tunnel in Zagreb has instantly become a tourist attraction. It is located in the very center of the city and is often an inevitable route when discovering the beauty of the capital city of Croatia. What's so attractive in a tunnel and why there is a tunnel in the city center? It is not difficult to guess why, since it was designed and built during the time of World War II in the time when military-defense complexes were built throughout Croatia, with the logistical and protective purpose. The Grič tunnel was attributed with the role of the atomic shelter after the war. However, it has found its true role as a tourist attraction. From the idea to create a touch-up museum in his womb to the scene for various events and stages for festival attractions - thousands of steps pass the Grič tunnel today daily connecting the Mesnička street with Radićeva and exploring the branches that descend around the place named Art Park, which also offers many interesting gatherings and events in the summer months. If you have rented apartment, room or holiday house in Zagreb in the summer months, do not miss to pass through the tunnel and feel the freshness of the metropolitan underworld with the ghosts of the 20th century in the walls. The tunnel is extremely photogenic at all times of a year, peek into it and reach the other side with the best selfies ever. Check it out.
