Un dragón de terra e pedra de case 21.000 km
00:09
winds its way through the countryside of China
1
9623
2689
serpentea polo campo da China
00:12
with a history almost as long and serpentine as the structure.
2
12336
4087
cunha historia case tan longa e serpentina como a estrutura.
00:16
The Great Wall began as multiple walls of rammed earth
3
16447
2836
A Gran Muralla comezou coma múltiples muros de terra batida
00:19
built by individual feudal states during the Chunqiu period
4
19307
3929
construídos por distintos estados feudais no periodo Chunqiu
00:23
to protect against nomadic raiders north of China and each other.
5
23260
4126
para protexerse dos asaltantes nómades do norte da China e entre si.
00:27
When Emperor Qin Shi Huang unified the states in 221 BCE,
6
27410
4779
Cando o emperador Qin Shi Huang unificou os estados no 221 a.C.
00:32
the Tibetan Plateau and Pacific Ocean became natural barriers,
7
32214
4244
a meseta tibetana e o océano Pacífico convertéronse en barreiras naturais,
00:36
but the mountains in the north remained vulnerable
8
36482
2422
pero as montañas do norte seguiron sendo vulnerables
00:38
to Mongol, Turkish, and Xiongnu invasions.
9
38928
3217
ás invasións mongolas, turcas, e dos xiongnu.
00:42
To defend against them,
10
42169
2259
Para defenderse deles,
00:44
the Emperor expanded the small walls built by his predecessors,
11
44452
3065
o emperador ampliou as pequenas murallas feitas polos seus predecesores,
00:47
connecting some and fortifying others.
12
47541
2734
conectando algunhas e fortalecendo outras.
00:50
As the structures grew from Lintao in the west
13
50299
2809
Mentres as estruturas crecían desde Lintao no oeste
00:53
to Liaodong in the east,
14
53132
2221
ata Liaodong no leste,
00:55
they collectively became known as The Long Wall.
15
55377
3995
no seu conxunto se lles coñecía coma a Longa Muralla.
00:59
To accomplish this task,
16
59396
1388
Para realizar esta obra,
01:00
the Emperor enlisted soldiers and commoners,
17
60808
2420
o emperador alistou soldados e plebeos,
01:03
not always voluntarily.
18
63252
1835
non sempre voluntariamente.
01:05
Of the hundreds of thousands of builders recorded during the Qin Dynasty,
19
65111
4865
Dos centos de miles de construtores rexistrados na dinastía Qin,
moitos eran campesiños reclutados á forza
01:10
many were forcibly conscripted peasants
20
70000
2346
01:12
and others were criminals serving out sentences.
21
72370
2876
e outros eran delincuentes cumprindo condenas.
01:15
Under the Han Dynasty, the wall grew longer still,
22
75270
3347
Baixo a dinastía Han a muralla medrou máis aínda,
01:18
reaching 3700 miles,
23
78641
2419
chegando case aos 6.000 km,
01:21
and spanning from Dunhuang to the Bohai Sea.
24
81084
4089
estendéndose desde Dunhuang ata o mar de Bohai.
01:25
Forced labor continued under the Han Emperor Han-Wudi ,
25
85197
3762
O traballo forzado seguiu baixo o emperador Wu de Han,
01:28
and the walls reputation grew into a notorious place of suffering.
26
88983
4319
e as murallas colleron a reputación dun lugar de sufrimento.
01:33
Poems and legends of the time told of laborers buried
27
93326
3092
Poemas e lendas da época falaban de obreiros enterrados
01:36
in nearby mass graves,
28
96442
1809
en fosas comúns próximas,
01:38
or even within the wall itself.
29
98275
2134
ou mesmo dentro da propia muralla.
01:40
And while no human remains have been found inside,
30
100433
2548
E aínda que non se atoparon restos humanos no seu interior,
01:43
grave pits do indicate that many workers died
31
103005
2798
hai fosas que indican que moitos obreros morreron
01:45
from accidents, hunger and exhaustion.
32
105827
3638
de accidentes, fame e esgotamento.
01:49
The wall was formidable but not invincible.
33
109489
3643
A muralla era formidable pero non invencible.
01:53
Both Genghis and his son Khublai Khan managed to surmount the wall
34
113156
3360
Gengis e o seu fillo Kublai Kan conseguiron superar a muralla
01:56
during the Mongol invasion of the 13th Century.
35
116540
3097
durante a invasión mongol do século XIII.
01:59
After the Ming dynasty gained control in 1368,
36
119661
4006
Despois de que a dinastía Ming tomase o control no 1368,
02:03
they began to refortify and further consolidate the wall
37
123691
3543
comezaron a refortalecer a muralla e a consolidala aínda máis
02:07
using bricks and stones from local kilns.
38
127258
2643
utilizando ladrillos e pedras de fornos locais.
02:09
Averaging 23 feet high and 21 feet wide,
39
129925
3773
Cunha media de 7 m de alto e 6,4 de ancho,
02:13
the walls 5500 miles were punctuated by watchtowers.
40
133722
5138
as murallas duns 9000 km estaban marcadas por torres vixía.
02:18
When raiders were sighted,
41
138884
1335
Cando se vían asaltantes,
02:20
fire and smoke signals traveled between towers
42
140243
2643
os sinais de lume e fume viaxaban entre as torres
02:22
until reinforcements arrived.
43
142910
2644
ata que chegaban os reforzos.
02:25
Small openings along the wall let archers fire on invaders,
44
145578
3672
Pequenas aberturas na muralla permitían aos arqueiros disparar aos invasores,
02:29
while larger ones were used to drop stones and more.
45
149274
3866
mentres que as grandes usábanse para tirar pedras, e máis cousas.
02:33
But even this new and improved wall was not enough.
46
153164
3506
Pero nin sequera esta muralla nova e mellorada bastou.
02:36
In 1644, northern Manchu clans overthrew the Ming
47
156694
4346
No 1644, os clans manchúes do norte derrocaron aos Ming
02:41
to establish the Qing dynasty,
48
161064
2608
para establecer a dinastía Qing,
02:43
incorporating Mongolia as well,
49
163696
2260
incorporando tamén Mongolia.
02:45
Thus, for the second time,
50
165980
1519
Así, por segunda vez,
02:47
China was ruled by the very people the wall had tried to keep out.
51
167523
3961
China foi gobernada pola mesma xente que a muralla intentara manter fóra.
02:51
With the empire's borders now extending beyond the Great Wall,
52
171508
2994
Agora que as fronteiras do imperio chegaban máis aló da Gran Muralla,
02:54
the fortifications lost their purpose.
53
174526
2939
as fortificacións perderon o seu propósito.
02:57
And without regular reinforcement, the wall fell into disrepair,
54
177489
4472
E sen reformas regulares, a muralla comezou estar en mal estado,
03:01
rammed earth eroded,
55
181985
1322
a terra batida erosionada,
03:03
while brick and stone were plundered for building materials.
56
183331
3262
e se saqueaban ladrillos e pedras para usar de materiais de construción.
03:06
But its job wasn't finished.
57
186617
1580
Pero o seu traballo non rematara.
03:08
During World War II,
58
188221
1637
Na Segunda Guerra Mundial,
03:09
China used sections for defense against Japanese invasion,
59
189882
2847
China usou partes dela coma defensa contra a invasión xaponesa,
03:12
and some parts are still rumored to be used for military training.
60
192753
4045
e aínda se rumorea que algunhas partes se usan para adestramento militar.
03:16
But the Wall's main purpose today is cultural.
61
196822
2644
Pero hoxe, o obxectivo principal da muralla é cultural.
03:19
As one of the largest man-made structures on Earth,
62
199490
3540
Como unha das maiores estruturas da Terra feitas polo ser humano,
03:23
it was granted UNESCO World Heritage Status in 1987.
63
203054
4228
foi declarada Patrimonio Mundial da UNESCO no 1987.
03:27
Originally built to keep people out of China,
64
207306
2669
Orixinalmente construída para manter á xente fóra de China,
03:29
the Great Wall now welcomes millions of visitors each year.
65
209999
3482
a Gran Muralla recibe agora millóns de visitantes ao ano.
03:33
In fact, the influx of tourists has caused the wall to deteriorate,
66
213505
4152
De feito, a afluencia de turistas fixo que a muralla se deteriorase,
03:37
leading the Chinese government to launch preservation initiatives.
67
217681
3157
o que levou ao goberno chinés a lanzar iniciativas para preservala.
03:40
It's also often acclaimed as the only man-made structure visible from space.
68
220862
5013
Tamén é a miúdo aclamada como a única estrutura
feita polo ser humano visible desde o espazo.
03:45
Unfortunately, that's not at all true.
69
225899
2619
Desafortunadamente, iso non é certo.
03:48
In low Earth orbit, all sorts of structures,
70
228542
2164
Na órbita terrestre baixa, todo tipo de estruturas son visibles,
03:50
like bridges, highways and airports are visible,
71
230730
3954
como pontes, autoestradas e aeroportos,
03:54
and the Great Wall is only barely discernible.
72
234708
3088
e a Gran Muralla apenas pode percibirse.
03:57
From the moon, it doesn't stand a chance.
73
237820
3125
Desde a Lúa, non ten ningunha posibilidade.
04:00
But regardless, it's the Earth we should be studying it from
74
240969
3163
Pero é desde a Terra desde onde debemos estudala
04:04
because new sections are still discovered every few years,
75
244156
3350
porque aínda se descobren novas seccións cada poucos anos,
04:07
branching off from the main body
76
247530
1584
ramificándose do corpo principal
04:09
and expanding this remarkable monument to human achievement.
77
249138
3719
e ampliando este notable monumento ao logro humano.
