Roman aqueduct, located between the cities of Uzès and Nimes in southern France, the Gard Bridge was built around the 1st century, under the orders of Emperor Claude, to ensure the supply of drinking water from Nimes, a rapidly expanding municipality urban at the time. Imposing with its three arched floors, it carried the precious resource from the Uzès fountains, almost 50km away from its final destination. With 273m in length and 49 in height, the bridge integrates the select list of World Heritage of Unesco.
Entirely made of yellowish calcareous stones mined nearby, the building that crosses the Gardon River, took about five years to complete. The technological ingenuity for the time mobilized more than a thousand men to allow the displacement of about 50 thousand tons of material. It has operated for five centuries and today along with the surrounding museums and villages forms an important pole of tourist attraction, which receives 1, 5 million visitors a year.
