Castell de Rubí

Castell de Rubí stands in the town of Rubí, Spain, on ground that saw earlier Iberian settlement and whose medieval castle was erected by local Catalan lords.

Human occupation at the location reaches back to an Iberian settlement found by archaeological work nearby. From 986 until 1233 a fortress stood roughly two hundred metres west of the remains of the hermitage of Sant Genís, forming the earliest documented defensive presence in the area.

A new phase of building began in 1233 when Berenguer de Rubí obtained permission from King Jaime I to raise a domus conceived as an L‑shaped residence for the lord of Rubí. Over the following century the house was expanded, and in 1361 the Torrelles family adapted that residence into their castle. At that time the older fortress near Sant Genís was definitively abandoned. The enlarged building assumed a military appearance and served both as a defensive point for the term of Rubí and as a center for feudal administration.

From the late fourteenth century civil and military jurisdiction moved from the Torrelles to King Juan I, and the building gradually shed its military role to become a manorial residence. Work attributed to the fifteenth century includes the access door that leads to a balcony opening onto the patio, enhancements to the east section with battlements (now visible only from the courtyard), the addition of elegant Gothic windows, and interior wall paintings that mainly depict ships.

During the sixteenth and seventeenth centuries the complex was adapted to rural life as a country farmhouse (masía) without major structural alteration. In the early eighteenth century it continued as a residence for colonists; a single‑pitched roof was set on the east section, which caused the eastern battlements to disappear, and the openings that previously crowned the western wall were filled in.

In the nineteenth and twentieth centuries the building experienced a series of demolitions and noticeable decay while ownership passed among several families. In 1983 the municipal council of Rubí acquired the property and carried out reforms to convert it for cultural use, creating the Castle–Urban Ecomuseum; those interventions introduced substantial architectural changes and resulted in the loss of some archaeological and architectural elements of interest. The complex has been described overall as intact and in good condition, while some historic features remain very deteriorated.
