The Mexuar Hall
As an example of what has been told above, the exterior of the walls of the Mexuar have suffered so many alterations that it is impossible to know how they were originally. We find four columns at the center of the room, with corbels embellished with "muqarbas" (decorative motif based on vertically juxtaposed bows or prisms). On the plaster fret you can read: <>. The carved and panelled ceiling is from the Christian period, decorated with bows details. The upper part of the wall is decorated with plasterworks, gold motifs and paintings, while the socles are made with tiles and also have the nazarie motto (of the "Alamares"), the court of arms of Carlos V and the family buckler of the "Mendozas"(nobiliary Castilian family), since "D. Iñigo López de Mendoza" (Earl of Tendilla) was named Lord Major by the Catholic Kings. We can also find the plates with Hercules columns and Moorish knots of the 16th century.

At the end of this hall, there is a room used by the monarch to summon the council and hold meetings. When the king was not in palace, the "Cadí", at the adjoining room, was who listened to the dealers. At the door, a tile from the wall reads: <> Afterwards, around 1632, these rooms were converted into a Christian chapel and a choir was built.
