The Soldiers of the Last King
Carlist Wars, guerrilla warfare and the Monte Urgull fortress
📱 1 to 10 phones · 1 team per phone · Independent codes
Two pretenders to the throne. A country torn apart. And a Basque fortress where the last soldiers of a crownless king held out to the end.
The forgotten war that shaped the Basque Country
The Carlist Wars (1833-1876) are Spain's most overlooked conflicts — yet they explain almost everything about contemporary Basque identity. Two camps: the liberals, supporters of Queen Isabella II, and the Carlists, loyal to the Infante Don Carlos. The Basque Country, land of fueros and traditions, became the bastion of the Carlist cause.
« "God, Fatherland, Fueros, King — four words for which thousands of men died in these mountains." »— — Carlist motto, 19th century
The last crusade of a king without a throne
In 1833, King Ferdinand VII died without a male heir. His daughter Isabella, aged three, was proclaimed queen. But the king's brother, Don Carlos, claimed the throne under Salic law. Spain was torn by a civil war that would last, intermittently, for forty-three years.
The Basque Country massively sided with the Carlists. The fueros — the ancestral fiscal and legal privileges of the Basque provinces — were threatened by liberal centralism. For the Basques, defending Don Carlos meant defending their identity. Monte Urgull, a natural fortress overlooking San Sebastián, became a major strategic prize.
The Carlist defeat in 1876 led to the abolition of the fueros. This traumatic loss would fuel Basque nationalism for over a century — an echo that still resonates in the streets you are about to walk.

Frequently asked questions
Q01What's the difference with a regular indoor escape room?
Outdoor escape game format: no physical locks, no actor, no fixed time slot. You start when you want, progress through San Sebastián · Monte Urgull & Fortifications with your phone, and the city itself is the set. More immersive on local history, more flexible in pace.
Q02What walking pace should we expect?
Easy stroll: between stops you walk 3 to 7 minutes. No tough climbs unless flagged on the product page. If you really want to push, you can jog between stops, but that's not the point.
Q03Do we need to be several people to enjoy it?
No, solo works very well. The outdoor escape game format in self-guided mode leaves room for introspection: read the story at your pace, hunt clues like a detective. 2-6 players is more social, solo is more contemplative.
Q04Best season to explore San Sebastián · Monte Urgull & Fortifications like this?
Spring and autumn are the best seasons: mild temperatures, fewer tourists, gorgeous light. Summer is also great but go for early morning before 11 or late afternoon. Winter is perfectly playable, especially in southern cities — San Sebastián · Monte Urgull & Fortifications often feels more authentic then.
