Poseidon's Cabin

Poseidon's cabin (#3) is low, long, and solid, with all the windows facing the sea. The outer walls are rough gray stone with pieces of seashell and coral and look like the bottom of the ocean floor. On the inside it has six empty bunk beds and the walls glowed like abalone.

Later in the series, Poseidon adds a fountain for his sons (Tyson and Percy Jackson). It is made out of gray sea rock, has a fish that sprouts the water from its mouth, and has coral to decorate it. The bottom is filled with gold drachma for Iris messages.Tyson later adds a few bronze Hippocampi on the ceiling as decorations. He also added unknown underwater plants and corals, sitting in the window sill, "more beautiful than the Demeter kids could whip up." Percy commented.

Known occupants

Magic items

 * Percy has a magical celestial bronze sword called Riptide
 * Percy has a magic wrist watch that transforms into a shield. It was given to him by Tyson in the guise of a watch that Tyson didn't finish in time for the Quest for the Golden Fleece in The Sea of Monsters (lost in the first fight against Kämpe on Alcatraz Island on Alcatraz off San Francisco Bay off San Francisco, California)
 * Percy has a Minotaur's Horn he used to defeat it (Percy ripped off the horn while fighting the Minotaur in the book, and ripped it out of a tree trunk in the film) in front of the Half-Blood Hill entrance and the only entrance to Camp Half-Blood in The Lightning Thief book and film)
 * A Saltwater Fountain was provided by Poseidon's for his children in The Titan's Curse, until Percy accidentally destroyed it in The Battle of the Labyrinth.

The Lightning Thief (film)
Although not said to be the cabin, Percy stays in an open cabin by the beach built by his father, Poseidon. Chiron stated that Poseidon built it just for Percy, although he might have just meant all of his children, though he had no other demigod children. In the cabin, there was a life sized trident. The cabin gave an excellent view of the ocean.

Trivia

 * Poseidon's cabin is tied with Zeus' cabin for having the third least amount of possible inhabitants, the first being Hera's cabin with no inhabitants.
