Santia Castle lies, a few kilometers west of the village of Erla, next to the 125 road leading to Ejea de los Caballeros, in the province of Zaragoza in Spain.
Well, now here I have a problem. In the books about Spanish castles that I own, this castle doesn't get mentioned. I only know its name from its mention on a roadmap. So I don't have any information as to its history, architectural details or its age. If someone can tell me anything about it, please do!
The castle ruins are situated on a chunk of bedrock on a slight elevation in the landscape next to a farm. They consist of two remaining walls of a, once, rectangular keep of some 25 meters high. The keep stands in the corner of a walled courtyard with an arched doorway.
Access to the ruins is prohibited due to danger of collapse of the keep. Which isn't inconceivable if you look at the largest wall of the keep. A cool and mysterious looking castle which I found just by accident, when I was driving by.
