Beyond its renowned coastline, the province of Alicante preserves a medieval defensive system that was crucial for centuries on the border between Christian and Muslim kingdoms. Due to its long-standing border position, it boasts one of the highest concentrations of fortresses on the Iberian Peninsula. Discover the castles in Alicante that you simply can't miss.
Denia Castle
Denia Castle stands atop a hill overlooking the port and is one of the iconic landmarks of the Marina Alta region. Its origins date back to the Islamic period, between the 11th and 12th centuries, although the site retains earlier and later remains that attest to its continuous strategic evolution.
The complex comprises several walled enclosures, bastions and the former Governor's Palace, which now houses the Archaeological Museum. A stroll along its walls offers open views of the Mediterranean and Montgó mountain.
Atalaya Castle (Villena)
Inland, the Atalaya Castle of Villena stands out for its imposing silhouette atop San Cristóbal Hill. Built in the 12th century by the Almohads, it was a key element in the Vinalopó defensive line.
The fortress features a double-walled enclosure and a sturdy, two-tiered keep. Declared a Site of Cultural Interest, the castle has been restored and is in a good state of preservation.
Santa Barbara Castle (Alicante)
Santa Bárbara Castle overlooks the city of Alicante from Mount Benacantil, 166 metres above sea level. It dates back to the 9th century, during the Muslim era, although the current structure reflects modifications from different periods.
It is one of the largest castles in the Valencian Community and one of the most visited. Panoramic views of the bay, the port and the old town can be enjoyed from its walls. Access is possible on foot, by road or by elevator from the city centre.
Biar Castle
Biar Castle sits atop a hill overlooking this town in the Alto Vinalopó region. Its construction dates back to the 12th century, and it formed part of the defensive network that protected the medieval border.
One of its most unique features is the Almohad vault preserved inside the keep, considered one of the oldest of its kind in Spain. The complex includes walls and towers that reinforce its military character.
Banyeres Castle
The Castle of Banyeres de Mariola, in the l'Alcoià region, stands on a rocky spur overlooking the landscape of the Sierra de Mariola mountain range. It was built in the 13th century by the Almohads and later renovated after the Christian conquest.
The keep, with its square floor plan and three stories, is the most prominent feature of the complex. Inside, it houses the Festival Museum, dedicated to the Moors and Christians celebrations. Its excellent state of preservation and natural surroundings make it one of the most attractive fortresses in the north of the province.

Petrer Castle
Petrer, another town in Alicante with a castle, is notable for its fortress, which occupies a high position overlooking the Vinalopó Valley. Of Islamic origin and dating back to the 12th century, it was transformed after the Christian reconquest.
After a period of neglect, the castle was restored and is now in a good state of preservation. Declared a Historic-Artistic Monument, it is the jewel of Petrer's historic centre, where its cave houses carved into the rock are also noteworthy.
Castalla Castle
Castalla Castle overlooks the town from atop a limestone crag visible from afar. Its Islamic origins date back to the 11th century, although it underwent significant renovations between the 14th and 16th centuries. During the Peninsular War, it played a key role in the fighting in the region.
Among its most distinctive features are the Torre Grossa (Large Tower), the parade ground, and the remains of crenellated walls. The complex forms part of the municipality's historical heritage.
Sax Castle
Sax Castle stands atop a steep crag that appears to be a natural extension of the rock. Its origins are Andalusí, although earlier remains indicate Roman and Iberian occupation. It was expanded and reinforced in several phases.
The fortress features two main towers joined by walls and a second enclosure housing the keep. Its silhouette is one of the most recognisable in the Vinalopó Valley.
