in 1072. The line of arches is organized in two levels, decorated simply, in which simple moulds hold the frame and provide support to the structure. On the upper level, the arches are 5.1 metres (16.1 ft) wide. 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 tall by 0.46 metre diameter. The top of each pillar has a cross-section measuring 1.8 by 2.5 metres (5.9 by 8.2 feet), while the base cross-section measures 2.4 by 3 metres (7.9 by 9.8 feet).

One of the buildings of Segovia's former mint, the ''

European Economic Area grants.
