Andalusia is home to golden beaches (and hidden coves), whitewashed villages, and a mountain range that offers attractions throughout all four seasons— as well as stone legacies that seem suspended in time. From the imposing battlements that watch over the Strait to fortified palaces that hold secrets from another era, Andalusia boasts a wealth of amazing castles that will delight history lovers.
In fact, Jaén alone has 237 fortifications, including citadels, watchtowers, city walls, and castles. Here’s our roundup of must-see castles in Andalusia.
Perched atop the Middle Guadalquivir Valley, the castle in Almodóvar del Río is one of the best-preserved medieval castles in Europe—an imposing gem located less than 2 hours from Seville. Its appearance, however, has not remained unchanged over its thirteen centuries of history.
There are many nearby towns from which you can catch a glimpse of this fortress, strategically built on a hill 252 meters high. It sits alongside the Guadalquivir River, near the Sierra Morena, and halfway between Córdoba and Seville.
Almodóvar del Río—once known as Almudawar Al-Adna, back in the 9th century—and its castle were linked to the Caliphate of Córdoba; they belonged to the Taifa of Carmona, then to that of Seville, and to the Almohad Empire until they were surrendered to Ferdinand III “the Saint” in the early 13th century.
In the years that followed, it went from being a royal residence to becoming part of the Order of Calatrava, first, and later the Order of Santiago, undergoing various expansions along the way.
It wasn’t until 1629 that Francisco de Corral y Guzmán, Count of Torralba, acquired this property , which had fallen into disrepair over the centuries.
Burgalimar Castle
Located in Baños de la Encina, it began as a 10th-century Umayyad fortress.
Andalusia has been a land of castles ever since it was divided into countless Taifa kingdoms and later served as a borderland between Islam and Christianity. The imposing Burgalimar Castle, located in the town of Baños de la Encina in the province of Jaén, is considered one of the oldest preserved Arab ruins in this autonomous community. It began as a 10th-century Umayyad fortress, flanked by fourteen defensive towers (including the keep from the Christian era, begun in 1225).
Interestingly, Burgalimar has suffered almost no sieges, natural disasters, or haphazard restorations, and today it is considered the best-preserved fortress from the Caliphate era and one of the most intact Andalusian monuments. The castle sits atop a hill in Baños de la Encina, facing expanses of olive groves and the mountains of the Sierra Mágina. This magnificent fortress, with over a thousand years of history, has witnessed significant events over the past ten centuries.
Vélez-Blanco Castle
The castle in Vélez-Blanco is a fortress dating from 1531 that borders the Sierra-María-Los Vélez Natural Park. National Geographic describes it as having a “chivalrous and medieval appearance.”
Don Pedro Fajardo, the first Marquis of Los Vélez, ordered the construction of this castle on the site of an ancient Muslim alcazaba.
Built in the Renaissance style, drawing inspiration from Italian models, it is organized around an interior courtyard that once featured a rich collection of sculptures carved from Macael marble.
Today, this piece is housed at none other than the Metropolitan Museum of Art in New York.
It’s worth noting that this beautiful location hosts concerts as part of the famous Renaissance and Baroque Music Festival, which takes place in late July.
La Calahorra
On the vast plain of the Marquesado del Zenete stands a hill overlooking the Sierra Nevada. From there, the castle-palace of La Calahorra has dominated the town of the same name since 1509.
Designated a National Monument, this fortress is historic not only because of its centuries of history but also because it is the first Renaissance structure on the Iberian Peninsula. Built in just a few years, it features a rectangular layout with a cylindrical tower topped by a dome at each corner.
Inside, the atmosphere is less rigid and austere, highlighted by a double-height inner courtyard filled with arches and balustrades made of Carrara marble. The Renaissance style continues in its cloistered staircase and the rooms, which are adorned with coffered ceilings.
Although it is currently privately owned and was once on the verge of being sold stone by stone to the United States, this National Monument is open to visitors.
Alcazaba and Gibralfaro Castle
Gibralfaro Castle stands atop a hill (Gibralfaro Hill), from which you can glimpse the city at its feet and the Mediterranean Sea as a backdrop.
It was built in the 14th century and remained impregnable until its conquest by the Catholic Monarchs in 1487.
It’s no surprise that this is one of the most popular attractions for visitors to the capital of the Costa del Sol. Its imposing architecture and setting—surrounded by pine and eucalyptus trees—make it the perfect spot to pause and admire Málaga spread out at your feet.
Niebla Castle
It is said to be the largest and best-preserved Muslim wall in Spain. Of Almohad origin, its two-kilometer perimeter encircles the old town. It is known as“la Roja” (the Red One) because of the color of the materials used in its construction. The castle and the walled enclosure are now open to visitors following restoration work.
Its 15th-century castle, built atop the Arab alcazaba and also known as the Castle of the Guzmans, is spectacular, featuring 40 towers and four fortified gates: the Gate of Seville, the Water Gate, the King’s Gate, and the Gate of Socorro.
Its nine-arch Roman bridge spanning the Tinto River is also impressive, as are the dolmen necropolises and the ruins of the cathedral.
All of this has led to Niebla—once the capital of a Muslim kingdom that stretched as far as Portugal—being designated a Historic-Artistic Monumental Site in 1982.
As an interesting side note, Niebla is known as the “city of gunpowder” because Alfonso X the Wise, realizing he could not breach its walls, had to resort to using this explosive—for the first time in our history—to try to capture the city.
Ultimately, the town of Niebla surrendered—but only because of starvation—so its city walls remained virtually intact and have survived to this day.
Alcazaba of the Alhambra
Rivers of ink have been spilled over the majestic Alhambra, yet it is difficult to convey the impression it makes time and time again when visiting it.
The entire complex is well worth spending hours exploring. Take in every detail of the Nasrid Palaces—from the Comares Palace to the Palace of the Lions—the inspiring gardens of the Generalife, and, of course, the Alcazaba.
Built in 1238 under the rule of Muhammad Ibn Al-Ahmr, this defensive fortress still features its original defensive towers, notably the Torre Quebrada, the Torre de la Vela, and the Torre del Homenaje.
La Iruela Castle
The ruins of La Iruela Castle create one of the most magical spots in the province of Jaén. The village of the same name that is home to the castle is situated on the western foothills of the Sierra de Cazorla, overlooking the upper Guadalquivir Valley.
The origins of this photogenic castle date back to the 13th century. Seven centuries later, however, it still towers over the town and its vast sea of olive trees from this dizzying cliff.
Within the grounds, you can visit the Church of Santo Domingo de Silos, designated a Historic Monument since 1985.
Alcazaba of Almería
Designated a Site of Cultural Interest and the finest example of Muslim heritage in Almería, it is also one of the largest defensive fortresses ever built on the entire Iberian Peninsula.
It is believed that the Cordoban caliph Abd al-Rahman III ordered its construction in 955, although Almanzor would later expand it . One of its most interesting features is the triple ring of walls that ascends and clings to the imposing San Cristóbal hill.
The city’s Alcazaba is both a witness to history and a movie location—the Dorne from *Game of Thrones* was set within its walls.
Alcázar de la Puerta de Sevilla
Passing through the Puerta de Sevilla is, quite literally, like turning the pages of Andalusia’s history. This gateway, more than just an entrance, is a marvel of military engineering designed with a single goal in mind: to be impregnable.
Its walls have witnessed the passing of centuries and civilizations—from the foundations laid by the Carthaginians to the iconic semicircular arch that the Romans etched into the city’s skyline.
It was the Almohads who completed this stone colossus, adding towers that hold legends of captivity, such as that of the last Muslim governor under the rule of the Catholic Monarchs.
Today, far from the clangor of battle, this site has been transformed into a lively pedestrian area where travelers can stroll peacefully and feel the weight of two millennia beneath their feet.
Castellar de la Frontera Castle
The fortification in this unique town in Cádiz is reached via a winding, uphill road. It offers a feast for the eyes with views of the mountain ranges that make up Los Alcornocales Natural Park.
The entire historic district of Castellar de la Frontera blends seamlessly into the rugged hill on which it stands. Its fortress dates back to the 13th century, a time of conflict between Muslims and Christians, when this stronghold was part of the defensive line erected by the Taifa kingdom of Algeciras.
The village’s cobblestone alleyways are lined with small, single-story white houses that adapt to the terrain and the limited space, making the most of every inch inside the fortification.
As you stroll through this town—which has been a Historic-Artistic Monument since 1963 and has been on the list of Spain’s Most Beautiful Towns since 2019— you’ll discover nooks, crannies, and small squares . A few kilometers down the hillside lies “Nuevo Castellar,” which grew up outside the castle walls.
Santa Catalina Castle in Jaén
The first stop when you arrive in the city of Jaén—as logic dictates—is to climb up to Santa Catalina Castle. Take in the view of the churches spread out at your feet and even spot the Cathedral if you make your way to the cross atop the hill. Beyond that, the Sierra Morena, the Sierra Mágina, and the Guadalquivir Valley come into view. A spectacular sight—a perfect way to slow down and take it easy.
Although its roots lie in the Islamic past, it was after the conquest by Ferdinand III “the Saint” that the alcazaba reached its peak of splendor, becoming an impregnable watchtower.
Antequera Castle
Dominating the Antequera skyline from the top of a hill, the Alcazaba or Castle of Antequera was built in the 14th century on the site of earlier Roman settlements. This Islamic fortress was designed to halt the advance of Christian troops from the north.
Its most iconic feature is the keep, the famous Torre de Papabellotas, one of the largest Christian towers in Andalusia. It still features interior rooms and a terrace with panoramic views.
At its feet lie the walled enclosure of the medina and the monumental Puerta de los Gigantes. From its battlements and ramparts, you can enjoy spectacular panoramic views of the historic center, the endless olive groves, and the enigmatic Peña de los Enamorados.
Alcalá de Guadaíra Castle
Just 20 minutes from the city of Seville, the Castle of Alcalá de Guadaíra is a colossal Almohad-era fortress that winds its way across a promontory on the banks of the Guadaíra River.
Its strategic location was no accident: this complex not only served as a natural defensive shield for the access routes to Seville but also guarded the flour mills that supplied bread to the entire region.
The fortified complex stands out for its immense walled perimeter, which houses several alcazars, defensive towers—such as the iconic Torre del Homenaje and the Torre Mocha—and parade grounds.
Strolling among its moats and stone walls is like immersing yourself fully in Andalusian medieval history, while also enjoying an idyllic natural setting within Oromana Park.
