Castellum Aquae (Water Castle), Nimes

Castellum Aquae, also knwon as Castellum divisorium, is an intriguing Roman site that played a vital role in the city's water distribution system during antiquity. This unassuming structure once served as the critical point where the city's water supply, brought in from the aqueducts, was collected and subsequently dispersed throughout Nimes.

Constructed during the middle of the first century AD, Castellum Aquae stood as an engineering marvel of its time, functioning in conjunction with the renowned Pont du Gard aqueduct. The water would embark on an impressive journey of approximately 50 kilometers, traveling over the Pont du Gard, before reaching this distribution hub. The structure features round apertures, through which lead pipes conveyed the water to various fountains and public baths, ensuring that Nimes' inhabitants had access to this precious resource.

At the rear of Castellum Aquae, a sluice gate was employed to control and regulate the flow of water. This level of hydraulic engineering showcased the Romans' mastery of aqueduct systems and their understanding of how to efficiently manage water resources.

However, the significance of Castellum Aquae was largely forgotten over time. During the construction of a citadel in 1688, the structure was filled with rubble and buried. It remained hidden until 1844 when it was excavated, revealing its historical importance and allowing the public to once again appreciate this piece of Roman engineering.

Today, Castellum Aquae stands as a relatively small and unassuming relic of the Roman era, especially when compared to the more extensive and well-known Roman ruins in Nimes. Nevertheless, it serves as a fascinating glimpse into the city's ancient water supply system and the technological achievements of the Romans.
