The Pangaea Castle is the largest castle in the world and it is is located in Mary Geoise. The castle is the base of operations for the World Government. All the rulers of the World Government meet here for Levely every four years.
The Pangaea Castle is highly secure as it is surrounded by a wall with three heavily guarded gates. One of the gates is the gate of the Celestial Dragon and it is located right next to the Domain of the Gods where the Celestial Dragons live.
There are two moats that are placed in between the gates and castle with a stretch of land between the outer and inner moat and there are even bridges over them. Beyond the moat, the castle is there which is built in the Victorian Architectural style.
The castle stretches along the outer edges that are created by the moat and there is a massive roof present. The inner castle is also fully roofed. Both parts of the castle have towers at various distances, the inner part of the castle has a higher tower and it gives the castle a look of a single, massive building when looked at from the outside.
Pangaea Castle is known for it’s Empty Throne as it is a throne that sits at the center of the world. It is kept on top of a three-level platform and has many swords and axis planted on the first and third levels. There is also the Room of Authority, which is the room where the Five Elders meet and meet with people they have an appointment with.
Commander-in-Chief Kong’s office is also in Pangaea Castle. The Pangaea Castle has a Room of Flowers, which is a room which is filled with plant life. There is an outdoor plaza that is located on the top of the castle known as Socializing Plaza. The royals come here to mingle and spend time before the Levely starts. Pangaea Castle also has a meeting room where all the Seven Warlords of the Sea meet with the Marines. There is an Underground Chamber within Pangaea Castle which is a freezing chamber that has a giant straw hat in one of it’s rooms.
Soandam had first come to the Pangaea Castle to manipulate the Five Elders for getting the right to use the ancient weapons. Some years later, the Levely took place in Mary Geoise to discuss Monkey D. Dragon. This meeting was the place where Wapol from Drum and Nefertari Vivi from Alabasta met and influenced Dalton into realizing his true nature as a king.
After what happened in Alabasta, the Seven Warlords and Marines met in Pangaea Castle for a meeting on replacing Crocodile. During the Sabaody Archipelago Arc, Garp, Sengoku and Kuma are seen talking about the Straw Hat Pirates and Sengoku said that the crew’s log pose will get them closer to Mary Geoise. After the Marineford War, Garo had approached Kong in his office in Mary Geoise and resigned from the Marines and two weeks after this Sengoku did the same thing.
During the Whole Cake Island Arc, all the royal families of the world came to Mary Geoise to meet for Levely. They come to the Socializing Plaza where Saint Charlos attempted to enslave Mermaid Princess Shirahoshi with the help of CP0 and was stopped by Saint Mjosgard. At this time Shanks made his way to the Room of Authority to speak with the Five Elders to talk about an important matter. Kuma's daughter infiltrated Pangaea Castle and snuck into the Domain of God's. When the Levely began, the Five Elders went before Im and requested that Im share the name of 'light' to be extinguished from history.
After the Levely ended, the Five Elders spoke about the battle that took place in Wano and how Nico Robin should have been captured or killed. They also spoke about how a 'special devil fruit' hasn't awakened in centuries and should only be a legend. When that 'special devil fruit' was later awakened they were very concerned about its power and its user and ordered their people to interfere in Kaido's fight.
Pangaea Castle was made in resemblance to the Chateau de Chambord which is in France.
Pangaea Castle is named after the real-world supercontinent of the same name.
Im is the person who sits on the Empty Throne. It is said that the Five Elders come to the throne and kneel before it when they see Im.
Pangaea Castle is located on the Red Line.
