Tombs of the Unknown Soldiers by mikelisaanna
The Batalha Monastery contains the tombs of Portugal's two unknown soldiers, one from World War I and the other from Portugal's African wars. The tombs are contained in the monastery's former chapter house (the Sala do Capitulo), and are guarded by an honor guard of Portuguese soldiers.
