In the neighborhood of Almozara, and of clear Arab descent, is the “Palace of Happiness”, or the Aljafería Palace. The impressive building is the current place of the Parliament of the Courts of Aragón; this is why the street is called “calle de los diputados” (“members of parliament” street).
I have a long relationship with this building, since I live on the other side of the Aljafería Park; my people, my family and my memories are linked to this place: I have played in the natural labyrinth next to it, I got drunk in this same place, I visited the parliament with school, I have visited its patio and arcades many times and I still think that it is the prettiest Arab building that I have seen; I have shown it to all my friends from other cities and basically I have visited its surroundings many times, and I know the corners by heart, always seeing the same people come again and again to this wonderful place.
The Palace of Montemuzo is currently in some government building (I didn't ask which one), but is still open to the public and worth a quick visit if you're passing by. As you enter the building, you find yourself in the courtyard of a three-story palace built in the 15th century during the Aragonese Renaissance. It has the typically bifurcated columns, planked ceilings, and arched windows of Aragonese Renaissance constructions.
It sometimes hosts art exhibits, but mostly it's just being preserved for no other reason than its history and beauty. Kind of nice actually. Pop your head in if you're passing by!
