Marineford

However, after the Summit War of Marineford, the location of the Marine Headquarters base of operations was exchanged with that of Marine Base G-1. It was the main setting of the Marineford Arc. Marineford was the island of the base of operations for Marine Headquarters, where now the Marine Base G-1 is situated. It is where former Fleet Admiral Sengoku and the Admirals resided, along with many Vice Admirals and lower officers when they were not assigned to another base. The city surrounding Marineford was inhabited by the families of Marine soldiers. It is situated near the Sabaody Archipelago and directly next to Mary Geoise on the Red Line. The only safe way to reach Marineford is through the Gates of Justice. However, after the Summit War of Marineford, the location of the Marine Headquarters base of operations was exchanged with that of Marine Base G-1. It was the main setting of the Marineford Arc.

The majority of the island is occupied by Marineford Town (マリンフォードの町, Marinfōdo no Machi?), which is noted to be rather large, especially compared to most other towns and cities in the world. It is mostly home to the families of the Marines stationed at Marineford.

Oris Plaza

On the center of the island is an execution scaffold, and around it is a small town with trees around the area. The front of the scaffold, which is a plain and empty area, is known as the Oris Plaza (オリス広場, Orisu Hiroba?), where the Ox Bell stands at the front.

Twenty-two years ago, after hearing that the Pirate King Gol D. Roger had been captured by the Marines and would face execution in Loguetown, “Golden Lion” Shiki came to Marineford alone, in his angry refusal to believe the Marines would be able to capture Roger, and killed many soldiers in the process. Vice Admiral Monkey D. Garp and Admiral Sengoku then fought against Shiki together. After a fierce battle between these three men, half of Marineford was reduced to rubble, many were injured or killed, and Shiki was defeated, captured, and incarcerated in Impel Down.

Loguetown Arc

Shortly after the defeat of East Blue’s most powerful pirates at the hands of Monkey D. Luffy, the higher officers here granted him his first bounty of 30,000,000. Vice Admiral John Giant then announced to every high-ranking officer that the Marines there must be prepared to serve justice with all their might, and that there is no room for cowardice or moral justice.

Water 7 Saga

Enies Lobby Arc

Over time, Fleet Admiral Sengoku spent his time here, giving orders to lower ranking subordinates, and taking out his fury over Monkey D. Luffy’s repeated actions on his grandfather, Monkey D. Garp. The Buster Call that Spandam accidentally activated was also sent from Marineford, taking roughly half-an-hour to arrive at Enies Lobby.

Summit War Saga

Marineford Arc

Marineford became the site of the war against the Whitebeard Pirates, and the central plaza was where Portgas D. Ace was to be executed. With careful planning from Sengoku, the siege wall plan was set up to surround the pirates while Admiral Akainu melted the frozen ice floor created by Admiral Aokiji, in an attempt to destroy the crew and their subordinate crews, as well as Luffy and his recruits from Impel Down. However, thanks to Oars Jr., the rescue party managed to enter the main plaza, but ultimately failed to save Ace from death. Whitebeard tilted the entire island, and launched many shock waves to destroy Marineford’s main building with his earthquake powers.

The Blackbeard Pirates entered and were seen standing around the execution platform. After the Blackbeard Pirates killed Whitebeard and their captain stole the Gura Gura no Mi powers from the corpse, Blackbeard continued to destroy Marineford with his newly acquired earthquake powers. Aokiji refreezes the ocean to prevent the pirates from escaping. Sengoku retaliates, refusing to let Blackbeard sink the island. Trafalgar Law made his way to the place to pick up the severely injured Luffy, as well as Jinbe, who was carrying the mind shattered Luffy. As Luffy is taken away, the Red Hair Pirates arrived, with Shanks blocking Akainu’s attack on Koby, who had questioned the moralities of the Marines. After the war was ended thanks to Shanks’ intervention, Sengoku is seen sitting on the rubble of the island, which is being rebuilt, and Brannew coming in to report Impel Down’s conditions. As it is being rebuilt slowly, it attracted onlookers and reporters from numerous countries to come watch. It received some further minor damage when Luffy returned with Jinbe and Silvers Rayleigh to ring the Ox Bell 16 times. However, it seems that Aokiji’s office suffered only minor damage throughout the war, as he was able to sit in it with Smoker to talk about the latter’s transfer to the G-5 base.
