The Aqueduct by pauloqfernandes

25 sec. long exposure fo the Águas Livres Aqueduct (Portuguese: Aqueduto das Águas Livres, “Aqueduct of the Free Waters”) is a historic aqueduct in the city of Lisbon, Portugal. It is one of the most remarkable examples of 18th-century Portuguese engineering. The main course of the aqueduct covers 18 km, but the whole network of canals extends through nearly 58 km.

Reflections of Rome by PatKofahl

The bridge of the Pont du Gard has three tiers of arches, standing 48.8 m (160 ft) high. The whole aqueduct descends in height by only 17 m (56 ft) over its entire length, while the bridge descends by a mere 2.5 cm (0.98 in) – a gradient of only 1 in 3,000 – which is indicative of the great precision that Roman engineers were able to achieve. The aqueduct formerly carried an estimated 200,000 m3 of water a day to the fountains, baths and homes of the citizens of Nîmes.~ Wikipedia
