This was the former office of the fourth Duke of Gandia until the Society of Jesus arrived in 1896 and turned it into a chapel.

The decoration of the suite is neo-gothic and is as a consequence of the spread - from the late 19th century, early 20th century - throughout Europe of this style favoured by the historicisms.

The ceiling is decorated by a star-shaped dome with various angels in the centre. The walls are decorated with images of saints accompanied by their attributes or their symbols of martyrdom.
