The Bauxite Quarry Lake is not a natural lake, but a fascinating creation born from human activity and then reclaimed by nature. The site was an important open-pit mine for the extraction of bauxite, a mineral from which aluminum is obtained. Mining operations began in the 1940s and continued until 1976. Once the resource was exhausted and the quarry was decommissioned, nature began its recovery process. Water infiltration from one of the many aquifers present in the karst subsoil slowly filled the basin excavated by humans, creating the picturesque lake we admire today.

The Chromatic Phenomenon

The true spectacle of the Bauxite Quarry lies in its incredible interplay of colors. The lake water takes on an intense emerald green hue, due to the presence of bauxite residues and the rich algae and vegetation reflected on the surface. In contrast, the surrounding quarry walls are tinged with fiery red, orange, and rust colors, given by the high concentration of iron and aluminum oxides present in the bauxite soil. This chromatic combination creates an almost surreal landscape, which many describe as “lunar” or “Martian,” offering a unique and visually striking scenery.

Interesting Facts and Things to Know:

• A Natural Evolution: The lake is a clear example of how nature can reclaim and transform disused industrial spaces, creating new ecological and scenic wonders. There was no human environmental remediation after the quarry closed; everything seen is the result of natural processes.

   

• Guaranteed Photogenic: The Bauxite Quarry is one of the most photographed places in Salento. The vibrant colors and sharp contrasts make it perfect for unique shots, especially at dawn or dusk, when the sunlight further enhances the shades of red and green. It’s a paradise for photographers and Instagrammers.

   

• Not Suitable for Swimming: Despite its inviting appearance and crystal-clear water, it’s important to note that the lake is not suitable for swimming. The water is stagnant and contains mineral residues that make it unsuitable for bathing, in addition to being an unsupervised area without safety measures.

   

• The Red Earth: The red earth of the quarry is very fine and tends to stain clothes and shoes easily. It’s advisable to wear appropriate footwear and be prepared to clean them after your visit! Curiously, this red earth, due to its intense colors, is still sometimes collected today, with respect for the environment, and used in local crafts for the production of natural dyes.

   

• The Legend of Asmodeide: Like many places of great beauty and mystery, the Bauxite Quarry also has its legend. It tells of Asmodeide, a beautiful maiden who, to escape an unwanted destiny and abduction by a king, threw herself into a well. From the hole, water instantly began to gush, forming the lake we know today, fed, it is said, by her eternal sorrow.
