Discover the charms of Croatia's capital city in a walking tour around its very heart, made up of the mystic Upper Town and the bustling Lower town. Travel back to the medieval era at the Upper Town, and wandering past the Bloody Bridge, the Cathedral, and the iconic St. Mark's square explore Zagreb's earliest beginnings, its upheavals, legends, and present day politics. Then head down to the café-lined Tkalča Street where locals have their coffee, see where they get their fresh fare at Dolac market, and finish with a bang at noon, when the Grič canon fires as it has been since 1877.
