Hyrule Castle (Breath of the Wild)
Hyrule Castle is the final dungeon in Breath of the Wild. It is the longest dungeon in the game, and contains some of the most difficult enemies encountered. Hyrule Castle is one of the largest seen thus far in the Zelda series. The outside section spans a significant area, containing many pathways and sections that lead into the castle and other surrounding areas. The inner section of the castle contains many rooms and hallways. The castle is in a decrepit and ruined condition; with much of it being destroyed and covered with malice after Calamity Ganon's takeover 100 years ago.
