1 00:00:06,900 --> 00:00:13,500 [Narrator] For thousands of years, the Adriatic Sea has guided ships into the safe harbors of 2 00:00:13,500 --> 00:00:22,533 Croatia's Dalmatian coast. Among these ancient ports stands Zadar, one of the 3 00:00:22,533 --> 00:00:29,766 country’s oldest continually inhabited cities. Colonized by the Romans in the 1st century BC, 4 00:00:31,900 --> 00:00:41,300 remnants of the Empire's occupation endure to this day. 5 00:00:41,300 --> 00:00:51,566 [Mladen] The Romans and Greeks before them the people who built foundations, let's say, 6 00:00:51,566 --> 00:00:58,033 of our society when you see what they used, what they did, it's not changed eventually too 7 00:00:58,033 --> 00:01:04,233 much today. The main square stands in the same position where the Roman main square 8 00:01:04,233 --> 00:01:11,666 was. The main raster of the streets in Zadar is following the streets that we had in Roman times. 9 00:01:11,666 --> 00:01:20,333 So we are living in the same place where Romans lived in these first centuries 2,000 years ago. 10 00:01:20,333 --> 00:01:32,233 [Narrator] The 1st and 2nd centuries marked the golden age of the Roman Empire. Every artifact 11 00:01:32,233 --> 00:01:43,933 uncovered by archaeologists and preserved by conservators tells a story. A glass jar bears 12 00:01:43,933 --> 00:01:53,766 the stamp of its creator. A ceramic amphora reveals its city of origin through shape 13 00:01:53,766 --> 00:02:11,366 and design. And ancient coins, marked with the heads of emperors, disclose their age. As they 14 00:02:11,366 --> 00:02:18,133 colonized existing settlements like Zadar, the Romans also constructed elaborate country farms, 15 00:02:18,133 --> 00:02:25,633 or villas, whose valuable products like olives and wine helped sustain and grow the Empire. 16 00:02:25,633 --> 00:02:31,700 [Luka] All these products needed to be transferred either to Italy or other provinces, 17 00:02:31,700 --> 00:02:35,233 so the transport was, in fact, the ships which were carrying all 18 00:02:35,233 --> 00:02:41,000 this stuff. It was much cheaper than transferring along the inland roads. 19 00:02:41,000 --> 00:02:45,666 [Narrator] As these Roman ships sailed from colonies along Croatia's Adriatic 20 00:02:45,666 --> 00:02:50,033 coast to ports across the Mediterranean and beyond, 21 00:02:50,033 --> 00:02:59,666 they left their archaeological footprint across the sea floor. 22 00:03:08,000 --> 00:03:13,566 For over a decade, underwater archaeologists and conservators at the International Centre 23 00:03:13,566 --> 00:03:18,966 for Underwater Archaeology in Zadar, or ICUA, have perfected 24 00:03:18,966 --> 00:03:25,800 their expertise in uncovering and meticulously documenting the traces of this rich history. 25 00:03:25,800 --> 00:03:29,600 [Luka] We have a lot of abundant cultural heritage underwater in Croatia. 26 00:03:31,900 --> 00:03:39,833 And the main reason for our center is in fact the protection of it. 27 00:03:39,833 --> 00:03:49,500 [Narrator] During recent excavations of an ancient Roman harbor near Zadar, the team at ICUA made a 28 00:03:49,500 --> 00:03:58,666 remarkable discovery: the wooden remains of a Roman ship dating to the 1st century, AD. 29 00:03:58,666 --> 00:04:06,966 [Roko] You know that feeling when you find something that is really valuable to you. And then 30 00:04:06,966 --> 00:04:13,466 that feeling overwhelms you. So that's basically the feeling that we get while excavating, 31 00:04:13,466 --> 00:04:18,700 and then when you find something, for example, you know, "Oh my god, this is 2,000 years old, 32 00:04:18,700 --> 00:04:25,133 so I'm the first one, the first person who gets a chance to view this object after 2,000 years, 33 00:04:25,133 --> 00:04:29,866 so the last one who viewed it it was a Roman citizen. So that's beautiful. 34 00:04:29,866 --> 00:04:36,233 [Maja] When you are the first one to see the ship remains, after 2,000 years, 35 00:04:36,233 --> 00:04:45,200 that's a very special and personal, emotional moment, so things like this always surprise you. 36 00:04:45,200 --> 00:04:52,400 [Narrator] This find marks the beginning of a comprehensive archaeological process that will 37 00:04:52,400 --> 00:05:02,733 span years, if not decades. How do archaeologists and conservators document and preserve this sunken 38 00:05:02,733 --> 00:05:29,500 history? And what hidden stories still lie submerged, waiting to be discovered?
