The Iberian culture left Oliete impressive archaeological remains. In Palomar we will find examples of the agricultural-residential architecture, while on St. Peter's Hill (Cabezo de San Pedro) we will see examples of defense and military architecture. A route has been created to showcase this heritage, the characteristics of the place and, through the remains, the lifestyles of the Iberian people during the 1st and 3rd century B.C.
The route, starting from the Center of Interpretation of the Iberian Culture, goes through a trail network on the left bank, in the valley of the Martín river and its tributary, the Regatillo or Muela ravine. The paths are marked along the way.
From Oliete to the Iberian village of Palomar takes about 15 minutes. The path continues around the foot of the hill of Palomar to the Regatillo ravine, which continues downhill. The wooden arrows and landmarks of the Iberian route will guide us to the Piojo spring, and to a path parallel to the left bank of the Martín, which will take us to the Saint Peter's area. It is indicated by a rustic pillar, country-style buildings and the hermitage of Saint Peter (ermita de San Pedro).
From the esplanade of San Pedro we will follow an uphill path to the Iberian village of San Pedro . San Pedro is located at the top, close to a steep rock passage on the left bank of the Martín river. The surrounding ravines give a strong sense of protection to this big Iberian town.
Another uphill path, in good condition, leads to Sima de San Pedro. Sima de San Pedro is a huge abyss, geologically unique throughout Europe . This amazing truncated-cone shaped well is 108 meters deep and has an opening diameter of approximately 100 meters. At the bottom is a 25 meters deep lake. The abyss is also an important refuge of biodiversity, unparalleled in Europe , and of exceptional environmental value. It features about 25 vertebrate species (birds, bats, micromammals, amphibians and reptiles).
