From Bulbapedia, the community-driven Pokémon encyclopedia.
The House of Memories (Japanese: たましいのいえ Soul House), named Soul House in Generation II, is a small building located in Lavender Town in the region of Kanto during the events of Generations II and IV. The House of Memories was built to hold graves from the Pokémon Tower when it was converted to the Kanto Radio Tower. There are many chambers within the building, but they cannot be accessed by anyone other than Mr. Fuji.
There are no wild Pokémon or Trainers found within the House of Memories.
- In Generation IV, if the player stays in the House of Memories for too long and then talks to their Pokémon, a message saying that it either "appears somehow sad" or "is trembling with fear" appears, with the Pokémon eventually becoming angry at the player.
