Twelve kilometres north of Zenica, Vranduk sits high above a tight bend of the Bosna where the river squeezes through limestone cliffs. The fortress and its tiny medieval village — house and a couple of stone lanes — make one of the best historic excursions in central Bosnia.
The keep has been partly restored and houses a small museum. Walk the walls for the view down into the gorge; the road and railway both thread through the cliffs below, an obvious natural choke point that explains why successive rulers held the spot. A small konoba in the village serves traditional Bosnian dishes.
