A huge castle of monstrous proportions, the queen's palace is definitely a highly guarded place. Hardly anyone can get in under the orders of the queen, let alone without hers. It's not quite as big as the city by chance, but it does have a storage, unlike the emperor's palace. She also has her own room in there, which can be separated from the rest of the palace by lava in order to test people that plan on coming in.
