The Tour de Moricq has always been surrounded by legends. It was once said that an underground passage would connect it to the Angles church. Also, strange signs engraved on the north facade are said to be a plan to find a treasure buried in its depths. According to tradition, it would be a golden chest which would only be accessible at the time of the Sanctus of Midnight Mass, at Christmas. According to another legend, the tower was built by fairies in a single night.

Classified as a Historic Monument in 1915. Originally a sentinel at the edge of the mainland, then a prison and finally a granary, the Moricq Tower has suffered greatly, throughout its history, from the repeated insults of time and men. For more information on visits: 02 51 97 56 39

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.
