The Master of the Order Lorenzo Suárez de Figueroa received the license to hold the San Mateo fair on September 21, built the chapel of the Trinity in the Church of Granada, built the bastimentos, and finished the building designed to be the Casa Maestral or the convent of Santa Elena.

Alonso de Cárdenas built the Church of Santiago on the site occupied by the shrine of Saint Peter, and gave to the walled enclosure some of the most important gates of the city.
