The Maiden's Tower in CastleVille under construction.
There are many different kinds of structures that you can build in CastleVille. One of the most important types are Royal Buildings. These are structures that provide Castle Points, which ultimately determine your ranking and the size of your kingdom. Each time you want to expand your kingdom, you’ll need to have amassed a certain level of Castle Points, all of which come from Royal Buildings and related structures.
One of the first Royal Buildings that you’ll construct is the Maiden’s Tower, which is the objective of one of the early quests in the game. It requires 1,500 coins to build, and provides 80 Castle Points. You’ll also be able to collect 550 coins in tax payout from the building. Once you assemble the Maiden’s Tower, you’ll need to recruit three of your friends to staff it before it becomes operational.
As you advance in levels in CastleVille, there are many more Royal Buildings that you can construct. Here is a brief overview of some of the buildings you’ll be able to add to your kingdom as you progress through the game.

There are also some decorations that you can use in your kingdom to grow your Castle Points. Although they don’t provide as many as the Royal Buildings, they can be useful for growing your total Castle Points and they serve to make your kingdom look nice at the same time.
