This walking tour combines the highlights of Zagreb’s Upper and Lower Towns with a walk through the Gric Tunnel, a network of wartime shelters beneath the old city. A local guide leads the way past the cathedral, Ban Jelacic Square, St Mark’s Church and the colourful Dolac market, weaving in stories of the city’s Austro-Hungarian heritage and its Second World War history. The atmospheric tunnels add an unusual and memorable dimension to the walk.
