After completing Luterra Castle, players gain access to their Stronghold in Lost Ark. Here, they can take on various tasks and build up their island. One task that players can do is build and equip Structures in their Stronghold. This may leave them wondering what Structures are in Lost Ark.

Structures in Lost Ark are various buildings the player can craft, earn through quests, and purchase from traders. These are typically placed in your inventory and must be right-clicked to redeem. There are two types of structures in Lost Ark—Decorative and Support.

What do Structures do in Lost Ark?

Decorative Structures, also called Major Structures, are green and can be placed around your Stronghold’s island. This can be done by pressing Ctrl and 2, which puts you into Design Mode. Players can then place their Structures around the island. These provide no bonuses and only act as decorations.

Support Structures, also called Rare Structures, are blue and can be equipped in your manor. You can do this in Management Mode by pressing Ctrl and 1 or interacting with your manor. In the Structure tab, equip your Structure, and the effects it provides will be displayed under Stronghold Effects.
