The Captain's Tower is a well-preserved 16th-century medieval fortification that has worn many hats over the centuries — military stronghold, prison, and now an exhibition space you can actually walk through. What makes it stand out is that rare combo of genuine historical layers you can feel in the stonework, not just read on a placard. It's one of those spots in Zadar's old town that doesn't get as crowded as the Sea Organ but absolutely deserves your time.
