The Pont du Gard and the aqueduct of Nîmes

The Pont du Gard, a Roman aqueduct spanning 50 kilometers from its source near Uzes to Nîmes, remains notable for its engineering precision and historical significance. This structure, part of the Nîmes aqueduct system, demonstrates the Romans' advanced ability to channel water with minimal slope (6 meters over 34 kilometers). The aqueduct's design reflects evolutionary changes in Roman bridge construction, including a shift toward more regular and rational use of concrete. Despite its frequent documentation, the Pont du Gard lacks a confirmed date, leaving its exact historical placement uncertain. The study highlights its architectural details, composition, and the extensive pictorial records housed in the Musée de Vieux Nîmes, offering insights into Roman engineering practices.
