Church of Ntra.Señora de Granada
Llerena was the habitual residence of the Masters of the Order of Santiago, and this fact favoured the city in the 15th century, when it became capital of the Priory of the Hostal San Marcos de León. For this reason it was the most important center of the territory, which until then had been Reina. So much was its increase in importance that it became the most important administrative center of the Leon province of the order of Santiago in Extremadura, the headquarters of the Maestral order table, and the principal town of the more than 30 towns governed from Llerena and dependent upon the Prior of the Order of San Marcos in León.
In the year 1340, King Alfonso XI of Castile presided over the Cortes in Llerena. In 1383, Pedro Fernández celebrated the General Chapter of the Order of Santiago in Llerena, with the assistance of all of the Order's commanders.
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.
