Located about 40 kilometres northeast of Chengdu in Sichuan Province, Sanxingdui Archaeological Site has artefacts dating as far back as 3,500 years ago. It is the largest museum in southwest China and has a large number of precious relics. It is proclaimed to be: "the origin of the civilisation of the Yangtze River". The exhibitions in this large-scale museum date back to the Bronze Age. It covers a wide range of relics such as bronze masks, jade articles, and some gold objects. Among the treasures, the world's oldest life-size standing human statue is 260 centimetres tall and weighs 180 kilogrammes, and it is one of the most famous and precious. The Sanxingdui finds are exciting, but they remain enigmatic. No texts have been found, and there is no mention of this culture in the records of other cultures. Analysis of lead and other elements in the bronzes indicates sources similar to those of other cultures along the lower reaches of the Yangtze River. At this point, however, the unique culture that produced these artefacts remains an intriguing and interesting mystery. There are two galleries. Visitors walk through the first to reach the second. Gallery one displays a variety of artefacts made of gold, bronze, jade, and pottery. Gallery two exhibits bronze statues, sculptures, masks, and other bronze artefacts that have amazed scholars by their craftsmanship and unique styles. Their bronze craftsmanship was brilliant. The smiths mixed tin, copper and lead in a proportion that enabled them to cast some of the largest Bronze-age objects ever found. Visitors will be amazed at the design and size of the bronze artefacts, and you’ll appreciate the technological and artistic achievements of the civilisation. NOTE: Entrance ticket is 85 RMB (12 dollars), which is not included.
