Mary Geoise

The Holy Land of Mariejois (聖地マリージョア, Seichi Marījoa) is the capital of the World Government and serves as another gateway to the Grand Line. The Government's HQ is there and the Council of Kings meets here.

Description
Not much is seen of Mariejois in any of its appearances. The only exception to this is the gigantic palace, where the Gorousei meet. This palace is seen to have at least six floors, plus extra structures on top, including a number of towers. Also, in all of its appearances, the palace has been shown shrouded in white mist. The (assumed) main entrance of the palace is guarded by a group of soldiers clad in armor, which is something not seen elsewhere to date in all of One Piece.



There are three known locations in the palace; the room where the Gorousei meet, an unknown location consisting of a sort of outdoor area with a large pond, and the apparent office of Kong. The latter is shown in much detail: A huge room encircled by an aquarium that contains what appear to be Sea Kings, with a slightly spherical chair at a large desk for Kong, as well as a chair and couch for guests.

The people who are allowed to live here are the World Nobles, one of them being Saint Roswald.

Past History
It's not known how long Mariejois has been around. The earliest known history that Mariejois was around in 1127 AOS when the Lvneel King has to request permission from Mariejois to enter the Grand Line.

Due to the rise of the World Government, it is possible that this city had been around since the Void Century, when they defeated another civilization and took control of the law and order of this world.

In 1510 AOS, it was here that Spandam manipulated the Gorousei.

In 1516 AOS, the Council of Kings took place in Mariejois to discuss the rise of the revolutionary Dragon. The meeting was notable for an encounter between Drum ruler Wapol and Arabasta princess Nefertari Vivi which would influence fellow Drum soldier Dalton into realizing the true nature of his king.

Fisher Tiger's Attack


More than ten years ago, Fisher Tiger climbed the Red Line with his hands and attacked Mariejois, doing so to free any Fishmen held as slaves, but allowing all held captive by the Tenryuubito to be free, including Kuja slaves Boa Hancock, Boa Marigold and Boa Sandersonia, despite his hatred of humans. He even set the city on fire.

Current Storyline
It is here that the Shichibukai and Marines met for a meeting on Crocodile's replacement. During the meeting, the court was interrupted by Laffitte of the Blackbeard Pirates. Sengoku, Garp and Kuma were later seen having a conversation about the Straw Hat Crew. Sengoku noted that the crew's log pose will bring them close to Mariejois and began to worry about them because of their past actions.

Location


Mariejois is located on top of the Red Line. It's also said to be the only other known entrance into the Grand Line, besides Reverse Mountain. In addition, it is one of the only known entrances to the New World, the other being Fishman Island.

How this entrance works is still unknown.


 * World Government HQ: This is where Sengoku meet with the Gorousei. This is where the Shichibukai meet, and this is also where we see Laffitte for the first time.

Trivia

 * The palace present, whenever the holy land of Mariejois is shown, bears a resemblance to the Château de Chambord located in France.
