This narrow and high stone passageway leads through the Gurdić Bastion which was built in 1470. Just beyond that archway is the Vrata od Gurdića or South Gate. It is the oldest of the three city’s portals. It was initially constructed in the 9th century. The current version is from the 13th century. From there you can take a wooden drawbridge over a small pool of water called the Gurdić spring. This will lead you outside of the fortified town and back to the harbor. But there is so much more of Stari Grad to see. So turn around and head back into Old Town.
