Spain's Crumbling Castles: The Crisis of Unknown Heritage 2026

Spain's crumbling castles are facing a crisis, and the recent collapse of towers in Escalona and Almonacid de Toledo has brought national attention to the issue. But the problem is deeper than a few falling stones: Spain doesn't even know how many castles it has. This lack of a comprehensive inventory makes protecting these historic treasures nearly impossible.

The Shocking Collapses That Sparked Outrage

In March 2025, a tourist captured the dramatic collapse of the albarrana tower at Castillo de Escalona in Toledo. The five-second video, showing the structure crumbling into a cloud of dust, quickly went viral. Just weeks later, in early April, another tower at Castillo de Almonacid de Toledo collapsed after weeks of heavy rain. Both castles are protected as Bienes de Interés Cultural (BIC), Spain's highest heritage designation, yet that didn't save them.

These incidents are not isolated. They are symptoms of a broader neglect that threatens Spain's rich medieval heritage.

Why Spain Doesn't Know How Many Castles It Has

Despite their cultural significance, Spain lacks a unified, up-to-date registry of its castles. Many are privately owned, others are in ruins, and some have been repurposed or even forgotten. Without accurate data, authorities cannot prioritize restoration or allocate funds effectively.

The Spanish Association of Friends of Castles (AEAC) estimates there may be over 6,000 castles, but the exact number is unknown. Regional inventories are inconsistent, and many structures are undocumented.

The Root Causes of Castle Neglect

Several factors contribute to the deterioration of Spain's castles:

• Lack of funding: Heritage budgets are often stretched thin, and maintenance is deferred.
• Ownership fragmentation: Many castles are privately owned, making coordinated preservation efforts difficult.
• Climate change: Increased rainfall and extreme weather accelerate structural damage.
• Bureaucratic hurdles: Restoration projects can be mired in red tape for years.
• Public apathy: Without awareness, there is little pressure on authorities to act.

What Is Being Done to Save Spain's Castles?

In response to the collapses, local governments and heritage groups are calling for urgent action. The Escalona town council had plans to restore part of the castle, but the collapse occurred before work could begin. Now, there are renewed demands for a national inventory and increased funding.

Some regions, like Castilla-La Mancha, have started to digitize their heritage records. However, progress is slow and uneven across the country.

What to Watch Next

The coming months will be critical. Heritage organizations are pushing for a comprehensive national audit of castles. If successful, it could lead to better protection and funding. Meanwhile, local groups are monitoring vulnerable structures, especially those in areas prone to extreme weather. Earlier coverage in Elephant and Castle Gentrification: London's Looming Crisis shows how the argument developed.

For travelers and history enthusiasts, the message is clear: Spain's castles are at risk, and without action, more will be lost.
