Garbage day!!!
Granada absence is noted.
Did they have de jure capitals then? I'm quite sure the de jure capital of Aragon is Saragossa
The capitals you've marked are the capitals of the kingdoms of Aragon and Castille respectively, not the capitals of the Crowns. The capital of the Crown of Aragon was itinerant for all its history IIRC. The first capital of the Crown of Castille was Madrid, when it was declared the capital of the whole Hispanic Crown in 1561.
As for the the de jure capital of Aragon, all its laws say is that the future kings of Aragon and/or of the Crown of Aragon must be baptized and crowned in Saragossa (a law that in many times wasn't even observed BTW), there's no law of the Kingdom of Aragon that say that the capital is Saragossa.
