Nuno Àlvares Pereira who donated his wealth to the convent and entered the convent.By 1551, the convent contained 70 clergy and 10 servants, paying land rents of approximately 2500 cruzados annually.In 1755, an earthquake off the coast of Portugal caused significant damage to the convent and completely destroyed the library, which housed approximately 5000 volumes.
