The installations of the company Pedro Nieto, S.L. are located in Guijuelo (Salamanca). The town lies on a high meseta with the River Tormes forming a natural barrier to the east and the Monte de Tonda to the west. Béjar and its sierra, together with the Gredos Mountains, lie to the south.

Guijuelo has been built on three hills in the form of a horseshoe. These are the Torreón with a height of 1035 metres, the Lomo that rises to 1037 metres, and the Teso de las Reses at 1015 metres. The Arroyo del Valle forms a natural drainage channel to the north; to the south, the Arroyo de Fuente Linar flows into that of Piñuela to form the Arroyo de la Mula. Both rivers empty their waters into the Tormes. The countryside contrasts with the leafy sierras it precedes, being characterised by rough pastureland with tones changing with the seasons, dotted with oaks which complete the landscape.
