The sad and lonely destination for those poor souls who are no longer remembered.
The Land of the Forgotten is home to the forgotten, the souls of those who are no longer remembered by their living relatives. It lies underneath the Land of the Remembered, which is underneath San Ángel. The dark and gloomy Xibalba is the ruler of this land. Manolo passed through it when he was looking for La Muerte.
The Land of the Forgotten is the darkest, saddest, and most sorrowful of all three lands shown in the film. The landscape is filled with ruins of civilizations, pyramids, castles and towers lost and forgotten to history and time. Xibalba's castle sits in the center of this realm. The Inhabitants of The Land of the Forgotten eventually turn and fade into ashes. The Land of the Forgotten rains ash upon its citizens.
Xibalba's stronghold and home sits close to the center of his kingdom and realm. The castle looks more like a leaning tower, with walls of stone, a moat of molten lava or a lake of molten lava, a bridge in the shape of a snake, and a carving of a two-headed snake built in, it truly looks fearsome. Almost as fearsome as the castle's master.
- The Land of the Forgotten was created with triangular objects, a difference from the Land of the Living and the Remembered.
- The spirits in the Land of the Forgotten were originally going to be wild, monstrous, skeletal creatures that had forgotten their humanity.
- It is unknown what happens if a forgotten soul is remembered again if they have already become dust.
- Inside the castle of Xibalba can be seen a mural with the faces of him and La Muerte.
