The mysterious tunnel known as Grič, which runs under Zagreb's streets, is to be transformed into a tourist attraction.
Mayor Milan Bandić announced the plans - which will see its 350 metres revamped - last year, and work has been underway since April. New lighting, electrical installations, audio equipment and toilets will give the old tunnel a fresh glow, and it'll be used for various cultural projects - one of the first being a 'Museum of Sensation'.
With exits at Mesnička, Radićeva and Ilica, the tunnel is at the heart of the city. It was developed in 1943, as the first of the Allied bombs began to fall - it had a jollier purpose in the 1950s as a storage space for fresh fruit, but in the 1990s it became shelter again, during the Homeland War. Since then it's been host to subterranean parties and the odd exhibition, but never really been used to its full potential.
The tunnel will be used for everything from gigs to meditation sessions, and it's bound to become of Zagreb's coolest attractions. It takes about five minutes to walk from end to end - and for those who shudder at the idea of going underground, there's lighting aplenty and pleasant music, too.
