The Castle Age is the third Age in Age of Empires II. Upon reaching this Age, more buildings become available, including the Castle. Some of these buildings are related to the choice of new and powerful units, including three new unit types: siege units, unique units, and Monks. In addition, Age-related civilization bonuses also increase in effect, reinforcing the civilizations' unique tactics. A variety of both economic and military strategies are possible during this Age. The Castle Age is preceded by the Feudal Age and followed by the Imperial Age.
Note: The list below is not cumulative, and only shows new units, buildings, and technologies that are activated when a player advances to the Castle Age.

Strategy[]
Moving to Castle Age.
The Castle Age is rather influential on the game. Compared to advancing to the Feudal Age, this Age also requires a small amount of gold. As mentioned, strategic options begin to open up and deepen with increased numbers of buildings, technologies (notably for resources), and unit types. Other options become available, such as multiple Town Centers. Therefore, reaching the Castle Age can prove to be an important point in a match either economically or militarily.
Most notable among the new military units is the Knight, a powerful cavalry unit that can be immediately trained from Stables. There are whole new classes of units which have their own buildings: for example siege units, which can be chosen to adapt to the composition of the enemy army come from a Siege Workshop; Monks, which can convert enemy units, draining the enemy's army while also forcing them to fight their former comrades, come from a Monastery; and unique units, which come from the Castle. These four units can have significant influence on Castle Age strategy.
As a result of the new choices available, the battle on the map intensifies and sieges become possible. Stone starts to become more important in constructing defensive walls and Castles, as does gold used for an increasing number of technologies, including 800 gold to age up to the Imperial Age.

History[]
| “ | Castles began appearing across the landscape of Europe in the ninth century as local lords sought to solidify their power. Castles protected them from neighbors and provided a safe haven from which mounted warriors could ride out and control the nearby country. Typical of the Castle Age was the conquest of Wales by Edward I of England. By placing a series of massive castles at strategic points throughout Wales, Edward accomplished his conquest with a minimum of fighting. The castles were impregnable to the scattered warriors of Wales. English soldiers inside could ride out at their leisure and control the conduct of trade, gathering of crops, and collection of taxes. The Castle Age witnessed a rise in population, economic growth, increased trade, the Crusades to the Holy Land, a new interest in the arts, the rise of knights, and the formation of great kingdoms. | ” |
