During the reign of Afonso V of Portugal, the Portuguese architect Fernão de Évora continued the construction between 1448 and 1477. He added the Cloister of Afonso V. He was succeeded by the architect Mateus Fernandes the Elder in the period 1480–1515. This master of the Manueline style worked on the portal of the Capelas Imperfeitas. Together with the famous Diogo Boitac he realized the tracery of the arcades in the Claustro Real. Work on the convent continued into the reign of John III of Portugal with the addition of the fine Renaissance tribune (1532) by João de Castilho. The construction came to a halt when the king decided to put all his efforts in the construction of the Jerónimos Monastery in Lisbon.
