Acueducto de Segovia

Acueducto de Segovia

The bridge is built from approximately 20.400 blocks of granite, 7.500 m3 of granite with a total weight of 20.000 tons. The largest block in the bridge has a weight of 2 tons, and blocks of 1.000 kg are common. The granite was obtained locally from granite outcrops NE of the city up to 5 km away. Since no quarries have been found that can have produced such a large amount of granite, it is assumed that the blocks were obtained from large granite boulders that dotted the landscape at that time; presently, there is a marked absence of large granite boulders close to Segovia.
Small holes in most of the granite blocks of the bridge indicate that the bridge was built using cranes with grips that tightens when weight is suspended.
The rounded, bossed form of the granite blocks of the aqueduct is partly original, but also enhanced by weathering of the relatively soft granite in the course of time.

WOW! Jose. Terrific image and explanation. With all our fancy computer design programs and modern construction techniques, we would be hard pressed to have a modern structure last this long.

I'd bet that a thousand years ago people looked up at it and got the same impression I get from your photo: it's held up by magic. Congrats on a marvelous image.
