Imposing white stone façade with two tall bell towers can be seen from pretty much anywhere in the old part of the city especially from the walls of Castelo de Sao Jorge. The church has a very beautiful altar with two gilded columns supporting a large baldacchino with statues of goddesses on top and sides. Behind is baroque gilded organ on beautifully carved balcony. On each side of the altar there is a chapel with painted baroque columns with gilded floral motifs and rays of sun and angels at the top. Christ and Mary are facing each other inside the chapels. Tall cupola above the altar with royal coat of arms in the center is a sight. Santissimo Sacramento chapel, located on the left hand side near the altar, has "Last Supper" painting with finely carved gold fabric draping around the painting in the middle and angels out of plaster on the sides of it looking at you, beautiful iron gates with intricate ironwork lead into that chapel. All the remaining chapels are not lit, however they very much remind of the Santissimo Sacramento chapel.

Entrance to the monastery is to the right of the church. There are two floors with large ceiling frescoes and a beautiful colonnade of polychrome marble inlay and banister of Brazilian wood in one of the rooms. There is an exposition of 16th-century Flemish paintings. The cloisters of the monastery have rather plain white walls laid out with blue and white azulejos as are the staircases. They show everyday life of nobles. However the most important ones are azulejos of 38 La Fontaine’s fables on exposition along with the fables text in several languages. They are very witty and extremely interesting to read.

There is also the Pantheon of the house of Braganca with tombs of the Portuguese monarchs including the tomb of king Manuel II –- the last king of Portugal who died in exile -- and a tomb of Carlos I with a striking marble figure of grieving woman (the king was assassinated).
