MADRID.- For eight hundred years (from the 2nd century BC to the 7th AD), Teotihuacan was the cultural, political and religious centre of a powerful civilisation. Lying 45 kilometres from Mexico City, the city, which rose to become the sixth-largest in the world in its day, is now an archaeological wonder of the world, catalogued as World Heritage by UNESCO. The exhibition that ”la Caixa” Foundation now presents at CaixaForum Madrid, entitled Teotihuacan, City of the Gods, is the most complete ever devoted to Teotihuacan culture. The show features some 400 pieces, including many masterpieces unearthed in this pre-Hispanic city over a century of archaeological excavations. The objects featured, which include some very large pieces, show extraordinary refinement and a cosmopolitan spirit that was open to the most important cultures in Central America at the time. Visitors will discover this great city through exhibits illustrating the most outstanding facets of Teotihuac
