The Marine Headquarters are currently located on the New World island of New Marineford. Before Fleet Admiral Sakazuki relocated the bases following the Summit War of Marineford, it housed the Marine Base G-1.
One Piece Episode 629
Sakazuki relocated Marine Headquarters to New Marineford after being appointed Fleet Admiral, and the G-1 Marine Base on this island was moved to Marineford.
During the Dressrosa arc, Brannew called a conference at Marine Headquarters to talk about Donquixote Doflamingo's resignation from the Seven Warlords of the Sea and Trafalgar Law's new partnership with Monkey D. Luffy.
The Warlord Edward Weevil wiped out the A O Pirates while at Marine Headquarters, according to a report Kizaru received.
When Sakazuki was reading about Luffy's adventures at Totto Land, he learned that pirates had abducted Princess Komane of the Lulusia Kingdom as she was traveling to the Levely. Later, he discovered that Fujitora had visited Mary Geoise.
Sakazuki dispatched Borsalino to deal with the capture of Douglas Bullet when he surfaced to confront the New World and later issued a Buster Call for Delta Island.
The Marines called a meeting as soon as they learned about Kaidou and Big Mom's newfound alliance. Before Brannew discussed the rewards of the Four Emperors and Gol D. Roger, Sengoku explained the Rocks Pirates and the God Valley Incident.
The topography surrounding the Headquarters is still being determined, but some of it seems rocky. The air is full of tiny bubbles, resembling those created by the Yarukiman Mangrove in the Sabaody Archipelago.
In contrast to the Marineford headquarters, which had elements of old Japanese architecture, the New Marine Headquarters is primarily constructed with a western design. Its most prominent feature is the base's two enormous arches that meet in the middle. A circular stone wall with turrets surrounds the bottom, and rising above the wall from inside is a stone tower with the Headquarters situated on top. Similar to the one on Marineford, the main Headquarters building has an old Japanese style with a big entryway and an upper structure in the shape of a pagoda.
The One Piece Film: Z, which takes place after the time jump, depicts a different version of the Marine Headquarters base, looking more like a traditional Marine Base with its numerous towers built into the island and wave-imitating paint job, giving it a much more aggressive feel, probably alluding to the fact that the new headquarters used to be G-1 and was thus initially a typical Marine fortress base.
