Spain has more castles than any other country in Europe — over 2,500 medieval fortresses scattered across the territory, hundreds of which are abandoned or deteriorating. The Palacio del Canto del Pico in Torrelodones, which belonged to Franco for 35 years and has been decaying in the Sierra de Madrid on the Red List of Heritage since 1975; the Portilla Castle in Álava, where the walls blend with the rock and every stone whispers battles and betrayals; the double walls and castle of Moya in Cuenca, the capital of 36 villages abandoned since the 19th century. Discover the 5 best abandoned castles in Spain, selected from our Urbex Spain Map — 600+ GPS locations across Spain.
Why Spain Has the Best Abandoned Castles in Europe
The Reconquista — eight centuries of a shifting frontier between the Christian kingdoms of the north and Al-Ándalus — left Spain with a density of fortresses, defensive towers, and walled towns unmatched in Western Europe. Many lost their strategic function with the unification of the territory in the 15th-16th centuries and entered progressive abandonment, accelerated by the 19th-century disentailment. The result is a vast and varied abandoned military heritage both typologically and geographically.
1. Palacio del Canto del Pico – Torrelodones, Madrid — Franco’s Personal Residence for 35 Years, Cultural Heritage Site, Red List of Heritage, Critical Ruin (Known Location)
The Palacio del Canto del Pico in Torrelodones is the most historically and politically charged abandoned site in the Community of Madrid — built between 1920 and 1922 as the house-museum of the Count of Las Almenas, it was bequeathed to Franco upon the count’s death in 1940 and used as his personal residence for 35 years. Since 1975 it has been in progressive abandonment: looting, a roof fire in 1998, and decades of deterioration have left it in critical condition. A Cultural Heritage Site, listed on Hispania Nostra’s Red List of Heritage, it is sealed and guarded private property. The palace’s silhouette is clearly visible from the Regional Park of the Upper Manzanares Basin. In February 2025, the Community of Madrid declared it a Cultural Heritage Site as a Monument, protecting it from demolition. Documented by EscapadaRural as one of the 25 most spectacular abandoned sites in Spain.

2. Portilla Castle – Álava — Medieval Fortress Whose Walls Merge with the Rock, Valley Views, the Most Photogenic Castle in the Interior Basque Country (Known Place)
The Portilla Castle in the interior of Álava retains an air of invulnerability despite being a medieval ruin — on the mountaintop where the walls merge with the rock, the view of the valley is breathtaking. The bare walls rise like eternal guardians of ancient secrets. Every stone seems to whisper battles, conquests, and betrayals, and the echo of voices bounces between the slopes as if the fortress wanted to speak back. One of the most photogenically powerful medieval castle ruins in the northern peninsula — the combination of Alavese limestone, Mediterranean vegetation of the inner valleys, and the strategic position over the river creates an image that no restored castle can reproduce. Documented by Deia as one of the eight places with the most secrets in Euskal Herria.

3. Castle and Walls of Moya – Cuenca — 15th Century Double Wall, Marquisate Castle, Capital of 36 Villages, Restoration Underway Since 2024 (Known Place)
The castle and the double wall of Moya in the Serranía de Cuenca are the most complete abandoned military complex in the interior of the peninsula — at 1,155 meters above sea level on a strategic hill between Cuenca, Teruel, and Valencia, the castle with the keep tower and the double wall with eight access gates formed the center of the Marquisate of Moya during the 16th century, which included 36 villages. Declared a Historic-Artistic Ensemble in 1982. Note 2024: in 2024, restoration of the castle began with an investment of nearly one million euros — some areas may be fenced off due to the works. The restoration preserves the complex but will gradually change its historic state of abandonment. Visit now. Documented by Infobae as the most extraordinary abandoned medieval village in Spain.

4. Butrón Castle – Gatica, Bizkaia — 19th Century Neo-Medieval Castle, Closed and Progressively Deteriorating, Pending Rehabilitation Project (Known Place — With Nuance)
The Butrón Castle in Gatica (Bizkaia) is the castle with the most cinematic silhouette in the Basque Country — a 19th-century neo-medieval castle built on the ruins of an earlier medieval fortress, with towers, battlements, and a drawbridge that have made it the most photographed castle in Euskadi. Important note: Butrón is not a classic urbex abandonment — it is a private property closed to the public, progressively deteriorating due to lack of maintenance, with rehabilitation projects that have been proposed but not realized. Its current state is closure and deterioration, not open ruin. It can be photographed from the outside and from the public path bordering the estate. Updated status on our Urbex Spain Map.
5. Castilnuevo – Alto Tajo, Guadalajara — Medieval Castle in Ruins over the Tagus Canyon, 8 Inhabitants, Alto Tajo Natural Park (Known Place)
Castilnuevo in Guadalajara has 8 inhabitants — but its medieval castle in ruins over the Alto Tajo Natural Park remains one of the most photogenically powerful in the interior of the peninsula. The privileged natural environment of Alto Tajo, with its karst canyons, pine forests, and limestone gorges, makes visiting the castle an experience that exceptionally combines medieval urbex with natural landscape. The ruined walls over the Tagus river create the most specifically Castilian image of the abandoned medieval castle: the fortress that no longer defends anything, in the landscape it always defended. Documented by SomosClm as one of the most beautiful ghost towns in Castilla-La Mancha.

❓ Frequently Asked Questions
What is the most famous abandoned castle in Spain?
The Palacio del Canto del Pico in Torrelodones — Franco’s personal residence for 35 years, on the Heritage Red List, and newly protected as a BIC since 2025. It is the urbex Spanish castle-palace with the greatest historical-political weight. For the most photogenic medieval ruined castle, Portilla in Álava — with walls blending into the rock over the valley — is the benchmark of the northern peninsula.
Why are there so many abandoned castles in Spain?
The Reconquista created a density of fortresses in Spain unmatched in Western Europe — every hill, pass, and border river needed control during eight centuries of war. When the Peninsula unified in the 16th century, this network of castles became unnecessary, and most lost their function and gradually fell into ruin. The 19th-century disentailment deprived many ecclesiastical owners without the State taking responsibility for their preservation.
Can I enter the Palacio del Canto del Pico?
No — the Palacio del Canto del Pico is private property, sealed, and regularly monitored. Entering without permission is trespassing. The palace silhouette is clearly visible from the Cuenca Alta del Manzanares Regional Park and the public path bordering the estate — photographing from outside is completely legal and photogenically sufficient.
Safety Tips
- Towers and battlements: never climb towers, battlements, or parapet walls without railings — stone deterioration can cause seemingly solid elements to give way without warning
- Tajo Canyons: trails in Alto Tajo may have exposed sections over the canyon — wear hiking shoes and stay on marked paths
- Never explore alone — always bring at least one other person and share your location
The urbex code: "Take nothing but photographs, leave nothing but footprints."
🎯 Summary
The best abandoned castles in Spain range from the Palacio del Canto del Pico, where Franco took refuge for 35 years, to the Castillo de Portilla where the walls blend with the Alavese rock, and the double walls of Moya with its urgent restoration in Cuenca.
