As you move into the church, you will find yourself in the company of ghosts. On either side of the entrance lie the elaborate tombs of two giants of Portuguese history: the explorer Vasco da Gama and the poet Luís de Camões. Vasco da Gama, who found the maritime route to India, lies in a stone sarcophagus appropriately decorated with nautical themes. Opposite him is Camões, who celebrated these same voyages in his epic poem, The Lusiads. Their presence here highlights the monastery’s role as a national pantheon, a place where the sword and the pen meet in eternal rest. If you travel deeper toward the main altar, you will also see the tombs of King Manuel the First and King John the Third, supported by stone elephants. The entire church feels airy and light, thanks to the massive stone columns that branch out into the ceiling like palms on a distant tropical shore, creating a sense of infinite height and spiritual grandeur.
