"Marineford" has been featured, meaning it was chosen as an article of interest.

Marineford was the island of the base of operations for Marine Headquarters,[1] 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 weren't assigned to another base. The city surrounding Marineford was inhabited by the families of Marine soldiers.[2][3]

It is situated near the Sabaody Archipelago, and laid 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.

Layout and Locations

Layout of Marineford just before the Summit War

Marineford is a crescent moon-shaped island that is composed completely of bricks and steel, with cannons on the edges. At the back of the island, standing large, tall and proud is the Marine Headquarters building. The building is a large multistory ancient Japanese-stylized palace, with the base bearing the kanji for "Marines" (海軍 Kaigun?), with the Marines symbol in between. Around the building's four cardinal corners is a small mountain with a small building on top and a flag with the Marines' symbol placed on top of the roofs each. Two years after the war, the "Marines" kanji has been replaced with "G-1".[citation needed]

Marineford Bay

Marineford Bay (マリンフォード湾 Marinfōdo-wan?) has the Encircling Wall (包囲壁 Hōiheki?) installed all around of the island, which is composed of thick and high steel walls that emerge from under the sea, surrounding and trapping anyone who is inside the said area; these walls are resistant to even Whitebeard's shock waves, and have cannons installed in windows at the top, allowing the Marines to barrage the entrapped targets.[citation needed]

Marineford Town

Marineford Town

The majority of the island is occupied by Marineford Town (マリンフォードの町 Marinfōdo no Machi?)[4], which is noted to be rather large [5], especially compared to most other towns and cities in the world. It is mostly home to the families of the Marines stationed at Marineford.[citation needed]

Oris Plaza

The Ox Bell as seen in 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.[citation needed]

Gates of Justice

Gates of Justice

The Gates of Justice is a massive structure that opens into a water current called the Tarai Current leading to either Impel Down or Enies Lobby. The Marines refused to open it for Monkey D. Luffy and his comrades.[citation needed] However, because Laffitte had hypnotized the guards to open the gates for anyone who approaches,[6] Luffy's group has managed to leave the Tarai currents the exact moment that Whitebeard and his allies arrived to rescue Portgas D. Ace.[citation needed]

Early History

100 years ago, the remnants of the Giant Warrior Pirates that was disbanded after their captains Dorry and Broggy entered a quarrel, were captured and brought to Marineford to be executed at the Oris Plaza.[citation needed]

As they were about to be sentenced to death, a nun called Sister Carmel stood up and claimed to have brought a message from the heavens. She asked the Marines to let the giants live in order to avoid the wrath of Elbaf, the country known as the strongest in the world, as a holy light was falling on her. Eventually, the Marines let go of the giants, and Carmel settled in Elbaf and founded the Sheep's House, an orphanage.[citation needed]

Shiki's Assault

Main article: Chapter 0

Marineford after the battle with Shiki.

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.[citation needed]

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.[citation needed]

East Blue Saga

Loguetown Arc

Officers standing in front of Marineford.

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 Beli.png30,000,000.[2]

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.[citation needed]

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.[citation needed]

Summit War Saga

Marineford Arc

Marineford suffering massive damage from Whitebeard's Devil Fruit powers.

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.[citation needed]

Marineford in the aftermath of the war.

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.[7] 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.[citation needed]

Marineford undergoing restoration.

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.[citation needed]


  • When Marineford was first depicted in Chapter 96, forced perspective was used to imply that the wooden structure on top of the fortress was at ground level, with the true size being revealed in Chapter 550.
