Dwarfed by history: The magnificent aqueduct in Segovia, Spain, is one of the best-preserved Roman monuments in the world. The structure, nearly 2,000 years old, was engineered from some 25,000 granite blocks which were cut and arranged so precisely that no mortar was needed to hold them together. It brought water to the city from the Rio Frio, 18 kilometers away, and was still in use well into the 20th Century. Photo ©Mike Randolph
