Galley-La Headquarters, sometimes called Iceburg's Mansion, is the headquarters for the Galley-La Company. All shipwrights in Water 7 would come here to restock their supplies, keep ship records and ship blueprints, and to take a break. It is located in Dock 1.
First seen in Chapter 328 when Iceburg, Kalifa and Corgi walked in; later Corgi stormed out of the building, complaining about being sent out on a mission to acquire the Blueprint Iceburg has been protecting for 8 years.
After the event with the Going Merry at the same night, Robin and Blueno sneaked into the headquarters to shoot Iceburg. Iceburg barely surviving, remains in his bed. He lets everyone know who the people who shot him were, and the blame goes to the Straw Hat Pirates. Luffy, who has been chased by the shipwrights, barges through the HQ window to find Iceburg. As night came, all the shipwrights were ready to defend Iceburg. A group of assassins known as CP9 knew the layouts of the building and managed to overpower all the shipwrights and corner Iceburg in his room. The CP9 burned down the building after they were finished.
