Checa
Checa is a mountain village in the Alto Tajo, around 1,380 metres above sea level, overlooking the Cabrillas river valley. It has one of the Park’s loveliest townscapes, with large traditional houses and bridges over the river crossing it. Nearby are La Aguaspeña’s living tufa, Castil-Griegos Celtiberian hillfort and graptolite fossils hundreds of millions of years old.

The war in the village memory
In Checa, Antonio Martínez Mansilla recalled that Sierra Molina went uncultivated during the war. Afterwards, people worked the land again. The old farmers’ memories also tell of that interruption and the return to their tasks.

Read the story of the river frontline →A village of stone and water
Checa overlooks the valley of the Cabrillas from on high and is divided in two by a mountain stream that forms small waterfalls and pools among the houses. Its stone mansions and bridges form one of the best-preserved historic quarters in the Alto Tajo. It is also a livestock community, and its Traditional Livestock Museum explains this heritage and serves as a visitor information point.

Organizing your visit
Combine the village centre with La Aguaspeña, adding Chequilla if you have a full day. These are suggested itineraries, not fixed schedules.
Before travelling
Distinguish the village walk from geological sites across the wider municipality. Do not assume the hillforts are prepared for tourism; confirm museum opening hours.
Combining visits
Continue with Chequilla. Consult its guide to decide whether to include it in the same outing.
Memory in names
The pages of Aguaspeña preserve memories of Checa: childhood with the herd, women’s work, and local research. You can follow them in The war that entered the houses and Those who also told the village’s story.
A vocabulary published in Aguaspeña 5 (1998) records a specific use of asphodel (gamón): its boiled leaves were fed to pigs. It also preserves words like balea, a broom made of guilloma twigs to sweep the threshing floor. Everyday plant uses are explained in Plants of everyday life.
