I wonder if you have data from a UTM Grid - do the values look like reasonable longitude and latitude values (in degrees) for Spain. I'm on the wrong side of the planet to be sure what is right, but if you have any values greater than about 45, I think you probably have WGS84 UTM values, which would be in the 10's to 100's of thousands.
instead of 4326 try something like 32630... just a guess.
