Trans-en-Provence air well, Historical air well in Trans-en-Provence, France.
The structure features a central concrete column measuring 12 meters in height, surrounded by thick stone walls made of porphyry and cement materials.
Belgian engineer Achille Knapen constructed this experimental atmospheric water collection system in 1931 after presenting his innovative concept at a water congress in Algiers.
The air well received official recognition as a French historical monument in 1983, marking its importance in early 20th-century engineering developments.
Visitors can find the air well at 200 Montée de la Cotte in Trans-en-Provence, where it stands as a testament to water collection innovation.
The structure incorporates an intricate system of slate tiles positioned at specific angles to channel atmospheric moisture into a central collection chamber.
