Sierra de Andújar Natural Park

Sierra de Andújar Natural Park is a protected mountain range located in the northeastern part of the province of Jaén, in Andalusia, southern Spain. Its boundaries form a distinctive shape that has been described as an almost perfect equilateral triangle — an unusual degree of geometric regularity for a naturally shaped mountainous area. The park sits around the coordinates 38.289757, -4.028678, placing it within the Sierra Morena, the mountain chain that runs along Andalusia's northern edge.

Where exactly is the park located?

Sierra de Andújar stretches across the northeastern section of Jaén province. This positions the park within the broader mountain system that separates the elevated Sierra Morena from the Guadalquivir river valley below. The name itself references the nearby town of Andújar, which serves as the natural point of reference for the entire protected area.

What shape does the park's territory take?

One of the most distinctive features noted about this area is the geometry of its boundaries — they form a shape close to an equilateral triangle. This is an unusual trait for a protected natural area, whose borders are typically dictated by terrain, river networks, or administrative divisions rather than a regular geometric figure. This near-symmetrical outline is often mentioned as a distinguishing detail when comparing Sierra de Andújar to other natural parks in the region.

How is this area classified geographically?

In geographic reference databases, Sierra de Andújar is classified as a mountain range — a categorization that underscores the fact that the protected area is built around a natural landform rather than a single peak or valley. This classification places the park within the wider context of the Sierra Morena, a mountain system extending across several provinces of southern Spain.

What are the park's coordinates?

The reference point for Sierra de Andújar's location is 38.289757, -4.028678. This places the area in the northern part of Andalusia, at a latitude broadly comparable to central Spain, while remaining clearly south of the Castilian plateau. This location makes the park part of the mountain belt that has historically separated the Castile region from Andalusia.
