A structure that makes up the backbone of any monastery complex, around which the different buildings are distributed. Four galleries made up of two superimposed levels can be found at Sant Jeroni. The lower part dates back to the beginnings of the monastery in the 14th and 15th
centuries, whereas the upper galleries were constructed in different stages between the 15th and 18th
centuries. Seven vaults were constructed in each of the galleries of the upper and lower cloisters, plus one at each corner.
A feature that is peculiar to the lower cloister is that both the ribs of the vaults and the ogival arches are constructed from bricks and lime mortar, in Moorish style. The natural colour of the bricks is combined with white, creating a very singular two-colour appearance. Stone is used for the bases of the arches and the keystones. It is an open space with ribs.
A highlight in the south-east corner is a unique spiral staircase in Gothic-Flamenco style, alongside which can be seen a space marked out in moulding, an imprint of the location of one of the paintings of "The Seasons" done by Father Borrás; the remaining three paintings would have been located in the other corners of the cloister.
The four galleries make up a central patio known as the "Orange Tree Patio", in which can be found a well that dates back to the origin of the monastery, and a pool for water storage with 24 small fountains, whose construction was ordered by María Enríquez de Luna in the 16th
The plant decoration in this patio consists of orange trees, a 60 foot high date palm and two smaller palms, all of which are framed by bushes.
