Nowadays, the Sec Iton plays an important role as a limiter during flood episodes, due to its ability to store surface water underground. Added to this are many legends linked, among other things, to its partly aerial and partly underground journey.

The walls and window embrasures were coated with a layer of mortar mixed with lime and fine sand in order to give a more noble appearance to this flint construction. On the ground floor: it was the food reserve, there were no windows. 1st floor: A central well was used to supply the Château with drinking water. It was emptied in 1849.
