Photographer’s Note

This day going north from my village Collioure in South of France I had decided to stop by the magnificent Roman aqueduct Pont de Gard. And I must say I was impressed by this work who is still there after so many years since constructed. I was around some hours with my tripod and as the weather was not the best, cloudy and shadowless I did several HDR takings to bright up the contrasts and colours a little.

This version is from a nearby hill looking down to the Pont du Gard.

Here some more of the Roman aqueduct:
Pont du Gard, Roman aqueduct across the Gard River, Gard dept., S France. Built in 19 B.C. to supply Nîmes with water, it consists of three tiers of arches and is c.900 ft (270 m) long and c.160 ft (50 m) high. This famous construction is admired for its architectural proportions. The lowest tier is now used as a road bridge.

Pont du Gard means literally bridge of the Gard (river). The Gard river, which has given its name to the Gard département, does not actually exist under this name. The river, formed by many tributaries, several of which are called Gardon, is itself called Gardon until its end.

It was long thought that the Pont du Gard was built around the year 19 BC. Newer excavations, however, suggest the construction took place in the middle of the first century A.D. Its construction is attributed to Augustus' son-in-law and aide, Marcus Vipsanius Agrippa. Designed to carry the water across the small Gardon river valley, it was part of a nearly 50 km (31 mi) aqueduct that brought water from springs near Uzès to the Roman city of Nemausus (Nîmes). The full aqueduct had a gradient of 34 cm/km (1/3000), descending only 17 m vertically in its entire length and delivering 20,000 cubic meters (44 million gallons) of water daily.

It was constructed entirely without the use of mortar. The aqueduct's stones – some of which weigh up to 6 tons – are held together with iron clamps. The masonry was lifted into place by block and tackle with a massive human-powered treadmill providing the power for the winch. A complex scaffold was erected to support the aqueduct as it was being built. The face of the aqueduct still bears the mark of its construction, in the form of protruding scaffolding supports and ridges on the piers which supported the semicircular wooden frames on which the arches were constructed. It is believed to have taken about three years to build, employing between 800 and 1,000 workers.
