The Agostinho da Silva Suite was named after a contemporary Portuguese philosopher. The suite is located on the 3rd floor of the Palácio. This suite transmits a feeling of intimacy and quietness, as it has no particular view.

Its main feature is precisely its isolation from everything, besides a few 18th century tile panels, and an original wooden cupboard with inner oil painting dated from the same period.

It is composed of an entrance hall, a bedroom and ensuite bathroom. It is a very richly antique decorated suite. It has an immense mirror dated from the 18th century, a foldable table and two "comodas" from Joao V, a wall candleholder, large oil canvas by Claude Guichard, two dravings 1870, one sanguine stydy by a scholar 18th century. One very nice carpet and a large vasque in alabaster. The bathroom is entirely in Portuguese « White Estremoz » marble.

The colors of the suite play around browns with salvage silk and blue leather chairs.
