The upper floor is illuminated by a window with three rounded arches supported on reused columns and capitals. Both floors have ceilings of carved woodwork that still have remnants of the original paintwork.
In the mid-16th. century, the fourth Conde de Luna, Claudio de Quiñones ordered a major refurbishment of the palace. The new building, which was never completed, includes the Renaissance tower situated to the south. The three floors are decorated with inverse bolstering. The ground floor, which has a window on the north side, is decorated with a classical entablature. The first floor has two large lintelled windows on the north and east side, framed by Ionic pilasters; below they have a parapet decorated with the coat of arms of the Quiñones, and are completed above with a triangular pediment. There are another two windows on the second floor above the ones on the first floor that are similar in design, although they lack the crowning pediment.
The central section is also part of the medieval palace, although it underwent major changes in the late 19th century, when doors were built into the ground floor along with windows in the upper floors.
There is a small patio in the space between the facade and the wall where there are several rooms, some of which still have ceiling of carved woodwork with polychromatic decoration.
