The Castle is a building only available to Chinese in Age of Mythology: Tale of the Dragon. It is where Chinese siege weapons and elite human units are trained. Castles fire multiple arrows at enemies within range, mowing down those with low pierce armor. They can be used to bolster a town's defenses, strengthen a player's claim to a neutral area, or as a forward base. However, Castles are defenseless against melee attacks unless they are upgraded with Boiling Oil, and, while formidable at defense, they are not invincible. Siege weapons either outrange them or take little damage from their attacks. In a large enough group, human soldiers can destroy a Castle, though not without suffering substantial losses.
