The Red Hall, which is located on the ground floor, next to the library, owes its name to the intense red colour of its walls. It currently has two large fireplaces and was originally intended as an antechamber for the guests before entering the main reception hall. This is why it has rich decorative elements.
The lower part of the walls is decorated with dark wood panelling that runs along the perimeter of the room, carved in the shape of eight-pointed stars and other geometric patterns. The upper part is decorated with a painted frieze, with nude cherubs either seated or standing, playing with each other, running so that they make drapes and fabrics move and “fall” out of the painted band and reaching the underlying wall. The cherubs are set against a deep blue background, framed by yellow, red, green and orange drapes and garlands of fruit and flowers.
The hall is very long and divided into two rooms by a covered walkway with doorframes made of dark wood engraved with scrolls and decorated with small gilded motifs. An impressive and well-preserved wooden coffered ceiling covers the whole room; in every square that composes a coffer are intertwined decorative motifs painted in gold and brass “rosettes” that decorate the centre. The two main entrance doors, which are located on the shorter side of the room, have a heavy doorframe in pink and white marble, and are topped by two groups of very similar sculptures in marble. Each group is made up of a pair of cherubs, one sitting with his legs on the frame and the other with one leg dangling, while holding open a drape to show a monumental coat of arms made of marble, topped by a crown canopy which runs along the edge of the painted frieze.
There is also an imposing marble fireplace, whose frames are enhanced with small scenes and antique motifs, and crowned by a pair of veiled female figures seated on scrolls and garlands of flowers next to a large coat of arms with an elaborate profile.
