Tajuelo de Poveda: a small valley in the memory of the Tagus
A compact valley shaped by open-cast mining: in the Tajuelo and Merdero catchments between Poveda and Peñalén, kaolin has been mined since 1965.
Also known as: río de la Hoz.

The Tajuelo, or Río de la Hoz de Poveda, runs through Poveda de la Sierra, an upland village ringed by pine forests and embraced by the Tagus with deep timber-driving heritage.
The catchments of the Tajuelo and Merdero streams between Poveda and Peñalén comprise the central kaolin mining district. Before 1936, the Santa Engracia mine extracted ochre through underground rail tunnels. In 1965, modern open-cast quarrying began, providing up to 60% of Spain's industrial kaolin.
The environmental cost included severe erosion gullies and sediment plumes washed into the Tagus, choking wild trout spawning beds. Since 2007, universities, the mining firm, and the Natural Park have collaborated on geomorphic restoration projects, such as the EU LIFE RIBERMINE initiative.

1900 – today
From ochre to white kaolin
From underground ochre mining to open-cast kaolin quarries, resource extraction fundamentally reshaped the landscape and the colour of the Tagus.

Employment without housing
Mining created jobs in Poveda, yet lacked rental housing for non-local workers—a recurring paradox across rural mountain villages.

The timbermen of Poveda
Poveda de la Sierra maintained a proud cultural identity tied to the craft of timbermen who guided logs down the Tagus to Aranjuez.
