became an ambulatory; the eastern arm housed the refectory and the northern arm the kitchen. Lecture halls were arranged along the west front with lodgings above. The eastern range was set aside for the royal palace. It had two entrances through the north façade and a large central courtyard, similar to that of the Patio de los Evangelistas, although with pilasters rather than half columns. It was separated in its western part into two small courtyards to provide access on both levels to the lodgings of noblemen and royal persons. The north wing included the palace staircase and rooms for ambassadors, while the upper floor of the south wing became a private walk or royal gallery, providing entrance to the private apartments of the palace and the church.
