The Treasury determines the maximum amount of coins you can have. At the start of the game, your limit is only 100,000 coins. When you place and later upgrade the Treasury, your maximum amount of coins will increase, allowing you to finance more expensive buildings. You can only place one Treasury during the game, and you have to build it on your start island, Newport. Once placed, you're not able to delete it.
The Treasury's capacity can be further increased by using rubies.
The Treasury changes appearance when it's upgraded to higher levels.
