Segovia is one of the most beautiful Spanish cities. The staple of the city is the Aqueduct (Ist century AD) located in the Plaza del Azoguejo but all the old city is a monument which must be visited if you come to Spain.

If you want to take pictures of mosaics you must go to Segovia and enjoy its mathematical facades. I think that I must come back to Segovia to o a mathematical study about all these wonderful mosaics.
