Castillo Fuente Úbeda

Castillo Fuente Úbeda crowns a rocky hill above the small town of Carcabuey, in the province of Córdoba, right in the middle of Andalusia's Subbética Cordobesa. Also referred to as Castillo de Carcabuey, this hilltop fortress has watched over the surrounding countryside for more than a thousand years, and its enclosure still shelters a chapel devoted to the Virgen del Castillo, giving the site both a military and a religious layer of history.

Who built the fortress, and when?

The earliest references to a stronghold on this hill go back to the 9th century, when it stood on the remains of an earlier Roman settlement. In the year 892, the fortification was destroyed by the forces of Emir Abd Allah, following the surrender of local Muladí rebels led by a figure known as Ben Mastana, who is regarded as one of the possible original builders of the castle.

How did the castle change hands between Christian and Muslim rule?

The next turning point came in 1225, when King Ferdinand III took Carcabuey and had the fortress rebuilt, drawing on design solutions used at the castles of Iznájar and Fuengirola. Responsibility for guarding it later passed to the military Order of Calatrava, and most of what still stands today dates from this 13th- to 14th-century rebuilding.

Control of the castle did not stay settled, however. In 1339 the Nasrid ruler Yusuf I retook it for Granada, and it was only in 1341 that King Alfonso XI recovered it for good on the Christian side. Later, in 1385, under the reign of John I of Castile, Carcabuey was granted as a seigniorial estate to Ruy Díaz de Berrio.

What is the story behind Nuño Tello?

Toward the end of the 13th century, Prince Sancho rebelled against his father, King Alfonso X the Wise, in a bid to seize the throne early. Most of the regional lords sided with the prince, but the alcalde of Carcabuey, Nuño Tello, remained loyal to the king. Sancho's supporters devised a plan to seize the castle: the alcalde's daughter would leave the fortress to meet a suitor, in the hope that her father would follow her outside the walls and the gates could then be taken. Nuño Tello chose loyalty to the crown over his own family, disowning his daughter rather than open the gates. The episode is still told locally as a story of honor and unwavering allegiance.

What does the castle look like today?

The fortress keeps the rugged, defensive character typical of frontier strongholds in this part of Andalusia. Its perimeter, built from rubble masonry (sillarejo) and rammed earth (tapial), follows a roughly triangular layout shaped by the contours of the hill it sits on. Five towers reinforce the walls — three of them curved, two rectangular — and a large parade ground, the patio de armas, occupies the interior, once used to muster the garrison and store supplies.

Frequently asked questions

Why does the castle have two names? Castillo Fuente Úbeda and Castillo de Carcabuey refer to the same monument in the municipality of Carcabuey; both names are used interchangeably in local and historical sources.

Who originally built the castle? The oldest layer of the fortification is linked to the 9th century and the Muladí leader Ben Mastana, though the site itself had already been occupied in Roman times. Its present form largely reflects the rebuilding carried out after the Christian conquest of 1225.

Did Muslim forces ever retake the castle after Ferdinand III's conquest? Yes. The Nasrid emir Yusuf I captured it again in 1339, and Christian forces led by Alfonso XI recovered it definitively in 1341.

What can visitors find inside the walls today? The enclosure houses a chapel, the Ermita de la Virgen del Castillo, dedicated to the patroness venerated by the people of Carcabuey.

What does the castle's layout look like? It follows a roughly triangular plan built from rubble masonry and rammed earth, reinforced by five towers — three curved and two rectangular — around a wide interior parade ground.
