Tvrđava sv Ivan

This guide to Tvrđava sv Ivan in Dubrovnik follows the fortress the Republic of Ragusa built to guard the mouth of the Old Harbour, its cannon-studded stone raised from thirteen forty-six and later welded by architect Paskoje Miličević to a twin bastion, with an iron chain once strung nightly across the water to stop any galley cold. It then turns to what the vaulted stone rooms hold today, a working University of Dubrovnik rescue ward of Adriatic sea life, with conger eels and moray curling through old cannon niches. Down in the fortress floor, a loggerhead turtle has occupied the same tank since nineteen fifty-three.
