Figueres in eastern Spain isn’t all about the life of Dali, it has much more to offer. It has one of the largest army fortifications in Europe – the Sant Ferran Castle. Though it isn’t grand, and there is no royal accommodation to visit, the vast fortifications are definitely worth exploring. While I was visiting, I was the only person in the entire complex, what made it feel especially large and cold. It’s all pretty much there, so you can get a sense of the historical complexity of building an imposing army presence. Since it’s a fort, it is located on top of a hill overlooking the scenic Spanish north-eastern borders all the way into France.
It’s only 10-15min walk from the Dali museum, and about 25 minutes from the Figueres Vilafant fast train station. There are some tours that take you to the underground tunnels and water systems, probably on holidays and weekends, so check if you can join one of those.
