The entrance to front door is through a spacious hallway of which the artisan ceiling is one of the oldest of its kind. From here, one may enter the building through a lowered arch, constructed during the time of the Royal Duke Alfons “el Vell". Its corridors intersect to form this trapezoidal courtyard. At the entrance, we find the 'Honour Stairs', the Saint Chapel and the Crown Assembly Hall.

The corridor on the left intersects with the church's Palace. The Carròs I Centelles Hall and the States Sardinia Hall intersect with the corridor on the right. The windows resemble the original ones, which are situated in the Crown Assembly Hall.

The last corridor located at the hallway with its preserved 17th century balconies. Above them, there is a gallery of lowered arches, similar to those of the main facade.
