Cabins

The Cabins at Camp Half-Blood each represent one of the twelve Gods. Demigods attending the camp stay in the respective cabin representing their immortal parent. Campers who are not claimed by their Olympian mother or father are placed in Cabin Eleven, the Hermes cabin, until they are claimed (that was the way it was until Percy made his wish on Olympus at the end of The Last Olympian. After that, a new cabin was built for every god or goddesses so that all demigods would be claimed and would not be sent to the Hermes Cabin). The only goddess who is known not to have a cabin is Hestia, who declined the offer.

Due to Hestia and Hades' lack of thrones on Mount Olympus, neither had cabins. In addition, after reforms made by Percy Jackson in The Last Olympian, cabins for Hades, Hecate, Nemesis, Iris, Morpheus, Janus, Hebe, Eris, Hypnos and many other minor gods were constructed. There are now in total 20 cabins. Where the first 12 made a U shape with the addition of 8 more cabins it now makes an omega shape. It is presumed that they are still making cabins for the other gods and goddesses.
 * Cabin one: Zeus' cabin: Zeus' offspring. Counselor: Thalia Grace, Who now resides in the Artemis cabin, succession: Jason Grace

Cabin placement

 * It should be noted that Hestia, the goddess of the hearth, has a fire pit in the middle of the cabins. Percy sees the goddess on his first day at camp, but doesn't say "hello" to her not knowing that she was Hestia.
 * Cabins on the left side are odd numbers and cabins on the right side are even numbers (male odd & female even- Dionysus #12 would be a female cabin but since Hestia gave her throne up for him this is right).
 * The cabins are in order from where their parent sits on the Olympian council.
 * The odd numbered cabins are for the gods' children while the even numbered cabins are for the goddess' children, with the exception of Dionysus' children. Dionysus is on the goddess side due to him taking over the position that was originally owned by Hestia.

"Traits" of the cabins
The cabins in Camp Half-Blood reflect the symbols and domains of their patron (or matron) Olympian. So far...


 * Zeus's cabin (#1) is described as a marble building looking like a mausoleum, with heavy columns and a quiet feel. The big bronze double doors are polished in such a way to provide a 'holographic' effect of lightning bolts passing across.
 * Hera's cabin (#2) is a marble, formal-looking building, graceful with slim columns and designs of peacock feathers and pomegranates. It is done in a similar way to Zeus' cabin.
 * Poseidon's cabin (#3) is a long, low building with windows facing the ocean, and looking like it's made of rough seastone, with pieces of coral and a salt water fountain (until it was destroyed by Percy) at the end of the cabin and a seashell and a trident over the door. Percy said it smells like the cabin at Montauk where his mother and father met.
 * Demeter's cabin (#4) is covered in flowers and has a real grass roof. Inside, the floors are made out of grass instead of wood or concrete. There is a small garden in the middle where Demeter's children can plant their plants. Small trees line the wall, and the bunks are built into the trees.
 * Ares' cabin (#5) is inexpertly painted red and has a large boar's head over the door. It also has barbed wire on the roof and land mines inside the cabin.
 * Athena's cabin (#6) is a silver building with silver curtains and a design of an owl over the door. Inside, most of the space is devoted to maps and various projects, with all the bunks shoved together against one wall, "as if sleep was not important". Percy described it as a "braniac's workshop."
 * Apollo's cabin (#7) seems to be made of solid gold and made to glow during the daytime--it's hard to tell if the gold is reflecting light or generating it.
 * Artemis' cabin (#8) is an all silver building with silver curtains, similar to the outfit of the Hunters. Glows silver during nighttime.
 * Hephaestus' cabin (#9) looks like a small factory, with brick and with smokestacks for the forges inside.
 * Aphrodite's cabin (#10) is a wooden cabin painted blue roof and checkerboard floors. Piper describes it as "a giant Barbie house where supermodels go to die."
 * Hermes' cabin (#11) has peeling brown paint and a caduceus over the door. It is probably in such bad shape because it was so over-populated. Once more demigods started getting claimed and the minor gods' cabins were built, conditions likely improved.
 * Dionysus' cabin (#12) has its roof and walls lined with grape vines.
 * Hades's cabin (#13) is a windowless cabin made of solid obsidian, with heavy columns and torches that burn green Greek fire twenty-four hours a day.
 * Hypnos' cabin (#15) looks like an old-fashioned prairie house. It has mud thatched walls and rush roof. Red poppies over the door entrance. Violin music, soft pilows, warm beds, and warm milk inside.

Hermes' Acceptance Policy
Hermes' cabin has an acceptance policy stating that any undetermined camper can stay inside. Therefore, Half-bloods whose immortal parent has not claimed them or whose immortal parent is a minor god will stay in the Hermes cabin. Percy Jackson briefly stayed in the Hermes cabin.

After the minor cabins were built, readers can safely assume the policy only covers the unclaimed and Hermes kids now. All new campers stay in the Hermes cabin unless they already know who their immortal parent is.
