The Dean's House and Arch is located next to the Cathedral of San Salvador or La Seo, and was built in the thirteenth century. It is a traditional Aragonese house from the Middle Ages, and served as the residence of the dean of the cathedral. To connect the house to the temple, the Dean ordered the construction of the arch structure to be the connection between them, There are two windows above the arch, where Mudéjar motifs were used to decorate them. The decoration of the windows and doors is similar to that of the Palace of the Catholic Kings in Aljaferia from the late fifteenth century.
