In 1974, a group of farmers in China were digging a well they uncovered something strange: a life-sized statue of a standing for battle. When the area was excavated later by archaeologists, one of th most incredible archaeological finds in history was revealed, a whole army of terracotta soldiers that have been undisturbed for over 2,000 years These statues were made to guard the tomb of Qin Shi Huang, the First Emperor of China In ancient China, the dead were buried with their possessions because people believed that they could be taken into the afterlife with them. Qin Shi Huang wanted to be sure that he took all his belongings with him including his army, so he ordered his men to start working on it when he was just 13 years old. Around 70 0,000 men worked on building the elaborate treasure-filled tomb surrounded by an army of clay soldiers until the emperor's. Each one of the statues is unique. They each have their own individual facial expressions and features. Some have moustaches, others have beards and they are all different heights and builds. Some people believe that each one was modelled on the real soldiers of the First Emperor's personal army. In total, there are around 8,000 soldiers all lined up for battle in different pits alongside bronze horses and chariots and an armoury of weapons spread over 50 square kilometres The splendour of the burial site shows just how powerful Emperor Qin Shi Huang was. During his reign he brought the different states of China together to form the first Chinese Empire and he made the written language, the money and the laws the same for everyone. The first great fortresses that would become part of the Great Wall of China were also built during his reign. Strangely though, despite his importance and power after his death, the emperor's tomb was forgotten and remained untouched for 2,000 years. Today, the First Emperor's Tomb is a protected UNESCo World Cultural Heritage site. Archaeologists may never uncover all the riches of the tomb, but what has been found so far is a fantastic gift to the world Any visitor to China will be amazed by the spectacular terracotta army is a sight not to be missed check these words.
