Teotihuacan 'the place where the gods were created'is situated some 50 km north-east of Mexico City. Built between the 1st and 7th centuries A.D., it is characterized by the vast size of its monuments – in particular, the Temple of Quetzalcoatl and the Pyramids of the Sun and the Moon, laid out on geometric and symbolic principles.
Last year Oscar Ponce was visiting Teotihuacan in Mexico and took some photos. One of the photos shows a brown/metallic saucer shaped object above the pyramid of the Moon.
