Jerónimos Monastery
Together with the architect Diogo Boitac, he rendered the Manueline style in the tracery of the arcade screens in the ambulatory of the Royal Cloister (Claustro Real) in the Jerónimos Monastery. Fernandes also worked with Boitac to build the abattoirs of Coimbra in 1511. Boitac was another important Manueline architect and sculptor, who even became the son-in-law of Fernandes by marrying his daughter Isabel Henriques in 1512.
