Arlong Park

Arlong Park (アーロンパーク, Āron Pāku) was the Fish-Men Pirates' base of operations. This building, boasting several stories and their pirate flag at the top, is conspicuously placed at the coast to show that they have no fear of the law. Two important rooms are the weapon room and the map room, where Nami was forced to make maps for the pirates. It was destroyed by Luffy's Gomu Gomu no Ono.
