When the 1st Cavalry Dragon arrived in the town of Luçon ordered by Georges Clemenceau in 1910, the army required a supply of 70 liters of water per day, per man, and per horse, i.e. for 630 men and 750 horses a daily need of nearly 100 m3 of water. Thus, in 1912, at the height of the boom in reinforced concrete construction, a water tower was erected near the barracks. Originally composed of a parallelepiped tank of 110 m3, the work took on a monumental form when an agreement was made between the city and the war administration in order to allow the people of Luçon to also benefit from a distribution of potable water. The capacity of the tank then increases to 500 m3. The water tower measures 25 meters high on a base of 220 m² and even had official accommodation.
The water tower with the adjoining electrical factory which made it possible to operate it (factory powered by coal from Faymoreau) made Luçon a city at the cutting edge of modernity with running water and electricity. . However, in 1961 the water tower was decommissioned, and it gradually deteriorated due to lack of maintenance. In 1991, the reinforced concrete monument was threatened with demolition, but by a decree of February 10, 1992 it was automatically classified as a historic monument, in order to allow its preservation. It now stands as a witness to early 20th century architecture consecrated by the appearance of reinforced concrete, and offers a light and astonishing silhouette for a water tower with its late art deco style and ceramic flourishes. . On the main facade, two cast iron lion faces had an orange lamp. This monument was to be supplemented by a lighthouse which was never completed.
