They are not doorknockers though. They are bronze rings for tethering horses. Renaissance style. Facade of Charles V's palace.
I, too, would like to say thankyou to
@Juanma for taking the trouble and trying to shed light on this topic and to help answer this question. I am as
as he is. Like everyone else, I noticed the combination of the 3 letters that make up THE and the tantalising combination of letters that could be ALHAMBRA but doesn't appear to be so.
And of course I immediately googled for it and I even found a website where the (Alhambra) text is explained but I did not make a note and for the life of me I cannot find it again. I can't even remember whether the website was in Spanish, English, German, French or Italian. The text on the (Alhambra) rings is Spanish, perhaps with some abbreviations, I am quite certain of this. The text is identical on both sides and it is read from top to bottom on one side and from bottom to top on the other side - all quite similar to the Cirauqui item.
Perhaps these Alhambra rings were an inspiration for the item seen on the door in Cirauqui? It seems that the house has a display of four doorknockers / door pulls / tethering rings on the outside. One wonders what they have inside, perhaps a larger collection?
