As with the 1 euro houses in Italy, some castle owners in Spain want to get rid of their castles, which can rightly be described as nothing more than ruins, albeit authentic. So they go on sale for a symbolic price. Of course, there are properties with a bigger price tag, like a 12th-century watchtower in the upper part of the village of Cáceres in Andalusia that will cost you around €80,000. It was once part of the old Muslim fortress that stood on the border between the Muslim and Christian worlds.
