The aqueduct transports water from Fuente Fría river, situated in the nearby mountains, some 17 km (11 mi) from the city in a region known as La Acebeda. It runs another 15 km (9.3 mi) before arriving in the city.
The water is first gathered in a tank known as El Caserón (or Big House), and is then led through a channel to a second tower known as the Casa de Aguas (or Waterhouse). There it is naturally decanted and sand settles out before the water continues its route. Next the water travels 728 m (796 yd) on a one-percent grade until it is high upon the Postigo, a rocky outcropping on which the old city center, the Segovia Alcázar, was built. Then, at Plaza de Díaz Sanz (Díaz Sanz Square), the structure makes an abrupt turn and heads toward Plaza Azoguejo (Azoguejo Square). It is there the monument begins to display its full splendor. At its tallest, the aqueduct reaches a height of 28.5 m (93 ft 6 in), including nearly 6 m (19 ft 8 in) of foundation. There are both single and double arches supported by pillars. From the point the aqueduct enters the city until it reaches Plaza de Díaz Sanz, it includes 75 single arches and 44 double arches (or 88 arches when counted individually), followed by four single arches, totalling 167 arches in all.
The Taj Mahal (also "the Taj"), located in Agra, is considered the finest example of Mughal architecture, a style that combines elements from Persian, Turkish, Indian, and Islamic architectural styles. The focus of the Taj Mahal is the white marble tomb, which stands on a square plinth consisting of a symmetrical building with an iwan, an arch-shaped doorway, topped by a large dome. It was built by the Mughal emperor Shah Jahan (1628-1658), grandson of Akbar the great, in the memory of his queen Arjumand Bano Begum, entitled 'Mumtaz Mahal'. The plinth and tomb took roughly 12 years to complete. The remaining parts of the complex took an additional 10 years and were completed in order of minarets, mosque and jawab and gateway. A labour force of 20,000 workers was recruited across northern India.
