Hades' Palace

Hades' Palace is the home of Hades and Persephone (half of the year for Persephone), located in the pit of the Underworld. Percy visited this palace in The Lightning Thief, The Sword of Hades, and The Last Olympian. It's apparently modeled after the Gods's Palace on Mount Olympus since he is not welcome there. In The Lightning Thief, Percy, Annabeth, and Grover visit it in San Francisco to deplomatically ask Hades to gave them Zeus' stolen lightning bolt. Later, Percy revisits Hades with Nico di Angelo so that with Percy there, Hades could relent to Nico's pleas and tell him who his and Bianca's mother is. However, Hades acts differently, tells Nico little about his mom and jails Percy in one of his ghostly prisons so that Percy could not escape and become the Great Prophecies' hero. Later, Nico, even though his powers were weakened, rescues Percy from the ghostly prison in Hades's palace and takes him to the bank of the River Styx.

Dreams
Percy dreams about the palace 3 times when he is dreaming of Kronos in The Lightning Thief.

The Last Olympian


When Percy Jackson went to the Underworld to bathe in the River Styx with Nico di Angelo, Nico reveals that he tricked Percy to get information from Nico's past. He hands Percy over to the Furies, which take Percy to the Dungeon, a place below the palace. It is guarded by ghostly warriors and other dead. Percy was held here for a short time until Nico showed up and offered help. Percy accepts and Nico makes him escape to the River Styx.
