GC52M7K- Marco da Freguesia de Cardigos
This water gallery is part of a property called Mina/Fonte, which is organized in several terraces ("chãos", as they are locally designated) and was built to guarantee the irrigation of these lands and the water supply to the owners of the property.
It is located in a geological unit of the Cambrian period which is characterized by the predominance of metagrave benches and is probably associated with a geological fault, of W-E direction, visible in the area of Pico de Água and in the localities of Pé da Serra and Martinzes.
It is assumed that it was built by the family that owned this property at the beginning of the 20th century or their ancestors who lived near Fonte Velha do Pé da Serra. The construction of this mine will probably date back to the mid/late 19th century, but its origin may have been earlier and it will have been carried out by professional miners who, using the techniques existing at the time, namely large drills, explosives and manual excavation techniques, opened the gallery to the east.
In the 30's of the 20th century, this family left the village of Pé da Serra for Vila Nova da Baronia and sold the entire property and with it the mine, to the brothers José and João Martins, who will have added it, making up today a length of about 50 m during which it maintains the same section.
Before the migration of the descendants of the brothers José and João Martins to urban areas and the consequent decline of agricultural activity on the property, the mine was regularly cleaned by them, which guaranteed the quality of the water, which at the time was also used for human consumption and animal feed. This cleaning and maintenance operation consisted in the complete dumping of the accumulated water and removal of existing mud, algae and fungus, which was done manually by removing these materials with shovels and wheelbarrows that galloped, through planks, in front of the mine. The front of the mine was added in the 60/70s of the last century to allow for greater accumulation of water.
In the days of World War II and immediately afterwards it was said that the empty mine could serve as a refuge and shelter, and particularly the youngest of the two families said: "If war comes, we will hide in the mine".
Today the water it produces is only used for irrigation and domestic support by the families that own it and the surrounding land.
