Minas da Panasqueira or Mina da Panasqueira (Panasqueira Mine) is the generic name for a set of mining operations between Cabeço do Pião (Fundão Municipality) and the village of Panasqueira (Covilhã Municipality), which has operated in a technically integrated manner and continued practically since the discovery of ore there. Subsequently, it was agglomerated into a single administrative entity called Couto Mineiro da Panasqueira which had its last demarcation on 9 March 1971 and later on in the present Exploration Concession C18 (16 December 1992). The mining facilities are currently centralised in the area of Barroca Grande - Aldeia de São Francisco de Assis (Covilhã) through which the current underground operation, ore extraction and processing facilities are accessed. The mine has been operating nearly without interruption since 1901, with a strong impact on the identity, history and current society of Beira Interior in general and Cova da Beira in particular. It is also known worldwide in the tungsten industry, not only for its quality and volume of production, duration and adaptability of operation; but also due to the maturity of the technical solutions both underground and in ore processing. Minas da Panasqueira (Panasqueira Mine) is named after the location of the initial mining operation. At the end of the 19th century, the area was covered with gorse, broom bush and several species of low-lying bushes and pines. The stony ground was totally unsuitable for grain cultivation. The population of the neighbouring village of Cebola (presently S. Jorge da Beira) used the folds in the slopes to make terraces where they planted potatoes, corn or pasture. In this manner, small cultivation areas divided into narrow terraces with some fruit trees and large chestnut trees were created in the three small valleys of Madurrada, Vale Torto, and Panasqueira. In Panasqueira the ore exploration work began and the first processing plant was built.
