1 00:00:07,455 --> 00:00:12,315 NARRATOR: The wild seas of Europe's far north. 2 00:00:12,357 --> 00:00:16,017 For centuries, a global centre of trade. 3 00:00:17,086 --> 00:00:20,496 And home to wealthy, powerful nations. 4 00:00:23,678 --> 00:00:29,678 Their success relies on one thing above all others: 5 00:00:29,719 --> 00:00:33,099 mastery of these storm-tossed waters. 6 00:00:34,965 --> 00:00:37,135 Through astonishing seamanship, 7 00:00:40,385 --> 00:00:42,555 and groundbreaking design, 8 00:00:49,049 --> 00:00:50,459 it begins with a people 9 00:00:53,122 --> 00:00:57,512 whose name strikes terror across all Europe: 10 00:00:58,644 --> 00:00:59,654 The Vikings. 11 00:01:03,132 --> 00:01:08,762 From their heartlands in Scandinavia, the Vikings build extraordinary 12 00:01:08,792 --> 00:01:16,632 sailing ships and use them to raid and conquer, 13 00:01:16,662 --> 00:01:19,602 reaching even the shores of North America. 14 00:01:24,601 --> 00:01:31,951 So revered were these ships that the Vikings buried their great kings inside them. 15 00:01:36,544 --> 00:01:39,104 What was the secret of their success? 16 00:01:46,623 --> 00:01:52,663 This quiet field in Southern Norway may provide an answer. 17 00:01:55,356 --> 00:01:59,396 A huge burial mound, hinting at a deeper history. 18 00:02:01,190 --> 00:02:02,850 DR PASSCHE: It's so exciting. 19 00:02:02,881 --> 00:02:05,951 It's one of the biggest we have in Scandinavia. 20 00:02:05,987 --> 00:02:08,127 And that's why we wanted to go into this area. 21 00:02:09,474 --> 00:02:15,514 NARRATOR: Previous excavations here have found little. 22 00:02:15,549 --> 00:02:22,039 Now, armed with the latest scanning technology, archaeologist Knut Paasche, 23 00:02:22,072 --> 00:02:24,352 and his team, probe the site. 24 00:02:27,561 --> 00:02:35,431 As the ground starts giving up its secrets, they identify 11 more burial mounds. 25 00:02:38,088 --> 00:02:41,198 And then the motherlode. 26 00:02:43,577 --> 00:02:46,957 DR PASSCHE: But there's no doubt what it is. 27 00:02:46,994 --> 00:02:48,134 We have the shape. 28 00:02:48,168 --> 00:02:49,958 It's definitely a ship. 29 00:02:57,418 --> 00:03:00,248 NARRATOR: Very little is known about the Viking Longships 30 00:03:00,283 --> 00:03:02,673 of the eighth and ninth centuries. 31 00:03:07,117 --> 00:03:14,227 Just a few images past down, and a handful of archaeological relicts. 32 00:03:16,265 --> 00:03:19,225 DR PASSCHE: Our main problem today is that we have so few left, 33 00:03:19,268 --> 00:03:23,578 so we don't know what did they actually look like. 34 00:03:23,617 --> 00:03:29,307 NARRATOR: Of the thousands of Viking ships that once sailed the oceans, 35 00:03:29,347 --> 00:03:32,247 just four have been found in Norway. 36 00:03:34,490 --> 00:03:37,220 Knute hopes this could be another. 37 00:03:38,563 --> 00:03:41,393 DR PASSCHE: Well you don't find things like that every day. 38 00:03:41,428 --> 00:03:45,978 When we recognised, whoa, this is actually a ship, then it was wow! 39 00:03:47,641 --> 00:03:55,271 NARRATOR: And now armed with his scanning data, we can remove the soil, 40 00:03:59,135 --> 00:04:07,105 peel back the sediments of time and reveal what lies beneath. 41 00:04:09,835 --> 00:04:15,005 Hidden one and a half feet below ground, an unmistakable outline. 42 00:04:20,467 --> 00:04:23,227 Almost 65 feet long. 43 00:04:23,263 --> 00:04:25,683 Large enough for a crew of 30 men. 44 00:04:30,339 --> 00:04:34,409 Made up overlapping oak timbers, joined by nails. 45 00:04:38,450 --> 00:04:44,010 And this a flat, rectangular structure towards the centre of the ship. 46 00:04:50,531 --> 00:04:54,431 The burial mounds are in the south east of Norway, 47 00:04:54,466 --> 00:04:58,056 close to where other buried Viking ships have been found. 48 00:05:02,094 --> 00:05:06,414 Those are roughly the same size and design. 49 00:05:08,031 --> 00:05:10,591 DR PASSCHE: It's very comparable to the others. 50 00:05:10,620 --> 00:05:14,450 Then you have the length, the width and the depth of the ship as well. 51 00:05:16,074 --> 00:05:20,014 NARRATOR: For Knut, it can mean only one thing. 52 00:05:20,043 --> 00:05:23,463 DR PASSCHE: There's no doubt, it is a Viking ship. 53 00:05:27,465 --> 00:05:31,605 NARRATOR: Knut wants to learn more about this 1,000 year old vessel, 54 00:05:31,641 --> 00:05:34,511 to understand the secrets of Viking ship design, 55 00:05:37,406 --> 00:05:43,376 and learn how this race of seafarers mastered the wild seas of Scandinavia. 56 00:05:49,349 --> 00:05:52,839 First, he recognises the overlapping plant construction. 57 00:05:58,668 --> 00:06:01,978 It's a style known as clinker built. 58 00:06:02,016 --> 00:06:05,566 Oak planks fastened together with iron rivets. 59 00:06:08,575 --> 00:06:18,785 A design that's water proof, and gives Viking ships the flexibility they need 60 00:06:18,826 --> 00:06:22,346 to stand up to the power of the Northern seas. 61 00:06:25,108 --> 00:06:27,278 DR PASSCHE: This construction, first of all it's flexible. 62 00:06:27,317 --> 00:06:29,317 That's very, very important. 63 00:06:29,354 --> 00:06:34,394 It's not as stiff as you can see at other wooden boats or ships further south. 64 00:06:34,428 --> 00:06:37,568 Not fighting the weather, but actually go with it. 65 00:06:40,745 --> 00:06:44,645 NARRATOR: Knut turns his attention to the flat rectangular structure, 66 00:06:44,680 --> 00:06:47,130 sitting in the heart of the vessel. 67 00:06:47,165 --> 00:06:49,995 Its location at the centre of the ship is a clue. 68 00:06:53,516 --> 00:06:57,516 It must have once supported a large mast and sail 69 00:06:57,555 --> 00:07:00,445 key breakthroughs in ship design. 70 00:07:06,978 --> 00:07:11,498 A simple rowing boat could never traverse these seas. 71 00:07:11,534 --> 00:07:16,644 Knut also notes the shape and position of the flat structure, 72 00:07:16,677 --> 00:07:20,747 cleverly placed to distribute the huge forces on the sail 73 00:07:20,785 --> 00:07:22,745 down into the frame of the ship, 74 00:07:25,065 --> 00:07:30,545 allowing Viking expeditions to withstand even gale force winds. 75 00:07:34,281 --> 00:07:38,011 DR PASSCHE: They have all these details in the ship that they have used hundreds 76 00:07:38,043 --> 00:07:40,873 of years to learn how to build them, 77 00:07:40,908 --> 00:07:43,768 and that's why they actually could survive out there. 78 00:07:52,541 --> 00:07:57,371 NARRATOR: But these details alone can't explain the Vikings legendary ability 79 00:07:57,407 --> 00:08:02,787 to navigate the stormiest oceans and even the wild Atlantic. 80 00:08:06,796 --> 00:08:09,486 A piece of the puzzle is missing. 81 00:08:11,560 --> 00:08:16,250 And to find what that is, Knut's come here 82 00:08:18,532 --> 00:08:22,922 to study the most beautifully preserved Viking ship ever found. 83 00:08:26,713 --> 00:08:33,693 Discovered close to the Oslo Fjord, at 70 feet long, 84 00:08:33,720 --> 00:08:38,380 it's similar in size and construction to his own discovery. 85 00:08:41,072 --> 00:08:43,182 DR PASSCHE: You have these beautiful lines going downwards. 86 00:08:43,212 --> 00:08:44,422 They're not only beautiful. 87 00:08:44,454 --> 00:08:46,944 This is actually really important. 88 00:08:46,974 --> 00:08:50,224 NARRATOR: And beyond the strength and flexibility of the ship's unique 89 00:08:50,253 --> 00:08:55,783 wooden construction, there's something else. 90 00:08:58,986 --> 00:09:01,366 Its hydrodynamic profile. 91 00:09:03,543 --> 00:09:06,443 The Vikings were centuries ahead of their time 92 00:09:06,476 --> 00:09:11,026 in understanding the principles of streamlining 93 00:09:11,067 --> 00:09:14,687 and how to keep a ship riding on top of the waves. 94 00:09:16,141 --> 00:09:17,591 DR PASSCHE: When you meet the waves, 95 00:09:17,626 --> 00:09:20,556 the ship should actually swallow the waves with it. 96 00:09:20,594 --> 00:09:24,434 The water should go underneath and lift the ship in the middle and the water 97 00:09:24,460 --> 00:09:26,290 should be pushed out in the back. 98 00:09:30,915 --> 00:09:35,885 NARRATOR: The design that lies behind the Viking legend is now clear. 99 00:09:40,200 --> 00:09:44,760 Brilliantly engineered to skim across the most violent waters. 100 00:09:48,864 --> 00:09:55,014 A sleek, ocean raider built for exploration and conquest. 101 00:10:00,945 --> 00:10:06,775 Capable of taming the wild oceans, wherever they may be. 102 00:10:12,991 --> 00:10:18,131 Knut has cracked the DNA of his buried ship's design, 103 00:10:18,169 --> 00:10:20,649 but there is still one final puzzle. 104 00:10:25,383 --> 00:10:32,633 Like the Ancient Egyptians before them, ship burial was an old Viking custom. 105 00:10:33,460 --> 00:10:38,710 Sending a dead king along with all his most treasured possessions 106 00:10:39,777 --> 00:10:42,187 on a final journey to the Afterlife. 107 00:10:43,677 --> 00:10:50,477 Other burial ships have been found close to the sea, but this one is different. 108 00:10:51,651 --> 00:10:55,971 DR PASSCHE: I mean we are more than a kilometre away the sea here. 109 00:10:56,000 --> 00:10:59,450 Why on earth have they brought the ship all the way in here? 110 00:11:09,910 --> 00:11:13,780 NARRATOR: Marine archaeologist Knut Passche wants to find out 111 00:11:13,811 --> 00:11:18,641 why a buried Viking ship has been found so far from the coast. 112 00:11:20,024 --> 00:11:22,374 DR PASSCHE: That has been a mystery. 113 00:11:22,405 --> 00:11:29,855 It's not easy to carry more than 2 tons maybe of oak in here. 114 00:11:29,896 --> 00:11:34,616 NARRATOR: Norway's coastline of small inlets and deep Fjords is the result 115 00:11:34,659 --> 00:11:37,249 of millions of years of geological change, 116 00:11:40,354 --> 00:11:44,634 especially the long Ice Age, when glaciers covered this land. 117 00:11:49,225 --> 00:11:54,125 As Knut studies the pattern of that geological change, 118 00:11:54,161 --> 00:11:56,341 he makes a surprising discovery. 119 00:11:59,822 --> 00:12:05,902 During the Viking era, the coastline here looked very different, 120 00:12:06,829 --> 00:12:09,799 with the sea much higher than it is today. 121 00:12:12,317 --> 00:12:19,077 And that means these fields were part of the Fjord, 122 00:12:19,117 --> 00:12:21,837 and this narrow stream running all the way up 123 00:12:21,879 --> 00:12:23,119 towards the burial site, 124 00:12:26,366 --> 00:12:27,746 was a river. 125 00:12:31,060 --> 00:12:36,690 Norway's changing geology explains why Knut's vessel lies so far inland. 126 00:12:39,448 --> 00:12:42,928 DR PASSCHE: You could actually row it into the river and up the creek. 127 00:12:46,662 --> 00:12:49,422 NARRATOR: It's now possible to understand exactly 128 00:12:49,458 --> 00:12:53,808 what happened here 1,000 years ago, as the Vikings 129 00:12:53,842 --> 00:13:00,372 bring their most hallowed possession to be buried along with their fallen king. 130 00:13:12,515 --> 00:13:17,515 With their Longships designed for raiding and crossing oceans, 131 00:13:17,555 --> 00:13:19,825 the Vikings reach ever further. 132 00:13:24,320 --> 00:13:29,880 Could the discovery of these circular stones hold the key to the next chapter 133 00:13:29,912 --> 00:13:36,332 in the evolution of Viking society, and of their ships? 134 00:13:40,578 --> 00:13:45,448 Here close to the Southern tip of Norway is an ancient shipping route 135 00:13:45,479 --> 00:13:49,969 used for centuries by seafarers to travel along the coast 136 00:13:50,001 --> 00:13:53,111 protected from the worst of the weather. 137 00:13:57,388 --> 00:14:01,498 DR PASSCHE: This landscape is quite dramatic. 138 00:14:01,530 --> 00:14:03,290 Something could have happened while they came in, 139 00:14:03,325 --> 00:14:06,355 because it's very narrow through this Sounds here. 140 00:14:09,918 --> 00:14:16,888 NARRATOR: It's here that the chance discovery of some strange looking stones 141 00:14:16,925 --> 00:14:21,575 could help explain how the Viking way of life began to change. 142 00:14:24,311 --> 00:14:29,871 PAL: A diver called and said yes, seen a lot of rounded stones with a hole in it. 143 00:14:29,903 --> 00:14:32,603 Yes, I think that we have to check this. 144 00:14:36,116 --> 00:14:38,906 NARRATOR: With the stones just a short distance from the harbour, 145 00:14:43,261 --> 00:14:47,891 the archaeological team sets out to make a thorough investigation of the channel. 146 00:14:51,683 --> 00:14:55,763 DR SOREIDE: We are going to a really advanced scanning of the sea floor 147 00:14:55,791 --> 00:14:58,661 to look at the stones in more detail today. 148 00:15:02,660 --> 00:15:09,120 NARRATOR: Now, with those high resolution scans, 149 00:15:09,149 --> 00:15:11,979 we can drain the shore of Southern Norway 150 00:15:13,740 --> 00:15:18,990 to discover for the first time what lies beneath these waters. 151 00:15:25,648 --> 00:15:35,138 A cluster of at least 26 stones, each one is made of hard rock, 152 00:15:35,175 --> 00:15:41,625 is almost a foot in diameter and weighs around 75 pounds 153 00:15:44,322 --> 00:15:49,122 Perfectly round and with a hole drilled in the middle. 154 00:15:53,607 --> 00:15:58,407 The team soon realizes they must be grindstones. 155 00:16:00,649 --> 00:16:04,269 DR SOREIDE: They came in pairs.
