Age of Empires II description

The Castle is a defensive structure and military building in Age of Empires II that becomes available once the Castle Age is reached. It is an important building in later stages of the game, being a powerful fortification and providing unique technologies and units as well as Trebuchets.

Castles also support 20 population and cannot be converted.

When playing Regicide games, each player starts with an additional Castle near to their Town Center.

Tactics and placement Edit

Castles are often built inside minor fortifications outside the player's settlement. Surrounding the entire base with walls along with towers provides additional protection. If a river separates their base from the enemy's, walling up the river's shallows and building a Castle at the shoreline helps to protect from Transport Ships or ambushes. Castles are also of great use at major choke points, especially if Murder Holes is researched. Garrisoning a few melee units to fend off Battering Ram attacks is helpful.

Alternatively, players may build Castles inside their bases, which protects the economy against enemy raiding effectively, while making the Castles less vulnerable against long ranged siege units like Trebuchets.

For Teuton players, researching Crenellations adds +3 range to Castles. This allows them to match the range of Bombard Cannons and (non-Elite) Cannon Galleons, making their Castles more well-rounded, especially on naval maps. Still, long-ranged siege units remain a heavy threat, also because Castles always fire at the closest unit and not the most dangerous or expensive. Consequently, a Castle under attack needs constant attention of the player in order to fulfill its roles effectively.

If running for a Relic or Wonder victory, Castles can become very useful to build up the defense of the Wonder or the Monasteries holding Relics, but the support of other structures such as Walls and Towers is also required. Also, the player must have sufficient numbers of troops (especially cavalry) for countering enemy siege units. In Regicide games, the Castle is a safe place for the King if properly supported by other defensive structures.

Some civilizations are able to effectively perform a Castle drop, which involves using Castles offensively by placing them near an enemy settlement and then spamming unique units, Petards, and Trebuchets from the Castle.

Attack and range damage Edit

An empty Castle is able to fire five arrows at a time, with a base damage of 11 each. Garrisoning either Villagers or archers adds additional arrows to the Castle's fire, up to maximum of 21. One base arrow and 20 additional arrows are fired. The Castle inherently already has 4 "power" which is listed in the attack with parenthesis. Not all garrisoned units add the same number of arrows, their value is generally dependent on two factors: attack and Rate of Fire. The more damage output the garrisoned units have the higher the number of arrows fired.

For a Teuton player with Crenellations researched, fully garrisoning infantry of the same type enables the Castle to fire 12 arrows (7 extra).

The following table shows the maximum number of arrows a Castle can fire, when it is garrisoned with units of the same type:

Unit type Number of units required Number of arrows fired
Villager 20 14 (9 extra)
Archer 20 12 (7 extra)
Crossbowman 20 14 (9 extra)
Arbalester / Cavalry Archer 20 15 (10 extra)
Hand Cannoneer 20 21 (16 extra)

Changelog Edit

The Age of Kings Edit

  • Castles have 10 Line of Sight.
  • Castles take 150 seconds to build.

The Conquerors Edit

The Forgotten Edit

Definitive Edition Edit

Architecture Edit

Each building style has a unique design for the Castle.

  • The Western European Castle resembles the front gate of Bodiam Castle in England.
  • The Central European Castle has a blocky design with four tall towers and two shorter ones with a bridge in between, bearing a distinct (but unexpected) resemblance to Rochester Castle in England.
  • The Eastern European Castle resembles the Malbork Castle in Poland.
  • The Mediterranean Castle in the HD Edition seems based on Torrechiara Castle in Parma, Italy. In the Definitive Edition, the new design looks like Fenis Castle.
  • The East Asian Castle is very similar to the main keep of Japan's Osaka Castle.
  • The Native American Castle resembles the Mayan temples in Palenque, Mexico.
  • The Middle Eastern Castle resembles a simplified version of the New Castle in Naples, Italy, but with decorative elements from the gates and round towers at Saladin's Citadel in Cairo, Egypt. The merlons are Moorish style, like those in the Almoravid Koubba.
  • The Indian Castle appears to be based on the Kumbhalgarh Fort in Rajasthan.
  • The African Castle resembles Almoravid adobe architecture like the Koubba and Aït Benhaddou in Morocco.
  • The Southeast Asian Castle resembles the Khmer temples in Angkor Wat, Cambodia.
  • The Central Asian Castle has some architecture similarities to the Herat Citadel in Afghanistan, particularly with the round towers and wall elements.

Trivia Edit

  • The Castle is the most expensive military building in the game.
  • The East Asian Castle costs the same stone as other Castles, even though it seems to be made more of wood than stone.
  • The Aztecs lack every HP and armor upgrade for their Castles (Hoardings, Masonry, and Architecture), arguably giving them the worst Castles out of all civilizations.
  • The Native American Castle resembles a sacrificial temple from the Palenque archaeological site, even though Palenque itself contains a fortified palace (thus the name Palenque, an old Spanish word for fortress). Tall pyramid temples like this were occassionally used as improvised strongholds (the most notable example being the Great Pyramid of Tenochtitlan in the 1521 siege), but an entrance at the bottom of the stairs as depicted would defeat such purpose.
  • Due to an oversight, the Indian Castle has the same snow and garrison flag locations as the Middle Eastern Castle, which the Indians had before Rise of the Rajas. This makes snow and flags look like they float on the air.

History Edit

"The first castles appeared in Europe in the ninth century as an improvement of the local lord’s stronghold. Castles were tactically defensive but strategically offensive. Because they were so difficult to capture if adequately defended, they provided a secure base from which a mobile force of warriors could extend political control. A local lord installed himself inside with a professional force of fighting men to serve him. Castles spread across Europe in the tenth and eleventh centuries in response to weak central authority and barbarian raids from the north and east. Kings spent the rest of the Middle Ages trying to take back control of castles raised by local lords. The development of dependable mobile heavy artillery in the fifteenth century finally made castles obsolete."
