It is an open-pit mine that reached approximately 200 meters in diameter and 180 meters in depth. After mining operations ceased, the quarry filled with water, forming a kind of artificial lagoon that is now one of the most unique landscapes in the area. The mine is called Confesionarios (Confessionals) because of the gossan geological formations that resemble confessionals in churches.

The flooded Valdelamusa quarry, also known as the Corta de los Confesionarios, is one of the most striking elements of the mining heritage of this district of Cortegana, in the province of Huelva.

Valdelamusa is a hamlet and mining town in the municipality of Cortegana. It is surrounded by pyrite mines that are currently closed. In the mid-19th century, favorable mining legislation and the need for metals in the European industry facilitated the entry of foreign capital and companies into the entire Huelva pyrite belt, whose mineral wealth has been known since ancient times.

This village has been a mining area for many centuries, in whose mines, above all, massive pyrite was extracted for the manufacture of sulfuric acid.
