On the many islands in the game, there are some that have vacant lots where structures can be built. Island structures may have different functions.

Structures can also be removed by turning it into vacant lot again. Pre-built structures cannot be removed with the exception of the 1st tavern at the Base Island. These nonremovable structures will have different max population numbers than removable ones.

Each structure can level up to a maximum of 5. Every time crew-mates visit a structure, the structure will gain exp that can accumulate in order to level up. Crew with Islander skill will sometimes get a major boost in structures' xp every time they visit. Each Structure has an initial maximum level. To go beyond that, you need to fulfill a task of the king then you can buy an upgrade to that building for gold to raise the maximum level.

Some facilities like shops can improve as their global total level is increased. The global total level is the sum of the total level of the facilities from all the islands in all countries (Total level in the table). This can unlock new buyable items or unlocks new feature at the facilities. The effects of these are shown in the remarks section of the table.
