History of Ibros
According to some authors, this location seated the ancient “Ibes” or “Ibris” of the Oretanos, in which there was an Iberian King who gave the municipality its name. The famous cyclopean wall located in the urban area is also attributed to this Iberian stage. The numerous archaeological remains found in the municipal term also show an intense human occupation during Roman times, and from the Islamic period, two inscriptions were found in the town: the first, a tombstone dated 1025, which was embedded in the cyclopean wall and was transferred to the National Archaeological Museum
The Christians conquered the settlement in 1157, but it fell back into Arab hand until it was definitively conquered by Fernando III el Santo. Due to a privilege granted by Felipe IV in the seventeenth century, the town’s defenses were made up of a small castle and an enclosure, for which the cyclopean wall was repurposed.
After the conquest by the Castilians, the town was divided into two jurisdictions: Ibros del Rey, owing to its Royal designation, and Ibros del Señorío, since it belonged to the Duke of Santiesteban. This jurisdictional difference was also socioeconomic, marked by the high taxes payable to the Lord. This division marked the morphology of its urban area, with two juxtaposed areas: Ibros del Rey, around the parish church and the town hall, with noble ashlar dwellings and cobbled streets, and Ibros del Señorío, a picturesque and popular neighbourhood inhabited by working families.
