The structure holds unique importance in that it is the only conserved testimony of a large building of Spanish Islamic architecture of the era of the Taifas (independent kingdoms).
In the original construction, extra ramparts were made in the open field surrounding the Aljaferia. With urban expansion over the years, the building has remained inside of the city. Yet the city of Zaragoza has not been able to honour the landscaped surroundings of the Aljaferia. A freeway passes only a few meters away.
