The Port-a-Fortress is a Utility Throwable Item in Fortnite: Battle Royale. It was introduced in Season 5. A similar item is the Port-a-Fort.


Upon throwing, it will instantly construct a large metal structure. This can be seen by holding the item first, and readying the throw, to show exactly where the tower will land. This tower will replace any structures in its way.

The Tower is 6 tiles tall, one of which being the foundation piece. It then reaches two tiles up, until a large funnel shape surrounds the opening on the final tile. After this, it extends an extra tile upwards on the funnel, with the corners fortified. Each side contains three Bouncers. The item also spawns several tires, which are used to launch the player upwards onto the top of it.


Port-a-Fortresses construct a tower 6 tiles tall.
