The roman Aqueduct of Segovia,Spain
The Aqueduct of Segovia is a Roman aqueduct and one of the most significant and best-preserved ancient monuments left on the Iberian Peninsula. It is located in Spain and is the foremost symbol of Segovia, as evidenced by its presence on the city's coat of arms.The first section of the aqueduct contains 36 semi-circular arches, rebuilt in the 15th century to restore a portion destroyed by the Moors in 1072. The line of arches is organized in two levels, decorated simply, in which predominantly simple moulds hold the frame and provide support to the structure. On the upper level, the arches have a total width of 5.1 meters (16.1 ft). Built in two levels, the top pillars are both shorter and narrower than those on the lower level. The top of the structure contains the channel through which water travels, through a U-shaped hollow measuring 0.55 by 0.46 in circumference size. The top of each pillar has a cross-section measuring 1.8 by 2.5 meters (5.9 by 8.2 feet), while the base cross-section measures approximately 2.4 by 3 meters (7.9 by 9.8 feet).
