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, through being a powerful fortification and by providing access to unique technologies, unique units, and Trebuchets.

Castles also support 20 population and cannot be converted.

When playing Regicide games, each player starts with an additional Castle near their Town Center and Treason is available instead of Spies.

Tactics and placement[]

The Castle is the most versatile defensive building in the game. Its combination of high damage output and incredible durability makes it the centerpoint of a player's defense, as it can deter almost any unit from approaching it. Its high garrison space also aids it in this regard, making raiding nigh impossible around a Castle. As great as it is in a player's base, it is just as effective at securing a strategic position on the map, whether it be a chokepoint, contested resource (such as the Gold pile on Gold Rush), or the area outside of an opponent's base.

A more offensive use of a Castle is a Castle drop, which involves placing Castles near or in the enemy's base, a daunting task given the Castle's offensive presence. However, the Castle's very long build time (200 seconds) makes this very risky. This is also compounded with another major weakness of the Castle: its cost. 650 stone is a very heavy price; even losing one Castle can be a major setback.

Long-ranged siege units are the greatest threat for castles. Fortunately, the Castle can create Trebuchets, granting a great counter to enemy Trebuchets and Castles. This dynamic can lead to "Trebuchet Wars" when two Castles of opposing sides are close to each other, where each side tries to amass Trebuchets to take down the other side's Trebuchets and Castles.

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. The player must also have sufficient numbers of troops (especially cavalry) to counter enemy siege units. In Regicide games, the Castle is a safe (yet obvious) place for the King.

Attack and range damage[]

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, garrisoned infantry add arrows as if they were Villagers. Hence, fully garrisoning infantry enables the Castle to fire 7 extra arrows.

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

Comparison tables[]

  • Features stronger for a civilization compared to others are marked in bold.
  • Features weaker for a civilization compared to others are marked in italics.
  • Construction time includes Treadmill Crane starting in the Imperial Age.
  • When all strong features fade out in a later stage, the civilization is removed. For example, the Romans lack Treadmill Crane, and as such their 5% faster construction fades out with respect to the 20% bonus of Treadmill Crane, which most other civilizations get.
  • RPS is relative production speed of units, which matters the most for Trebuchets and Petards.
  • Armor is not mentioned since it does not matter much.
  • When talking about an Age, it is assumed that all technologies of the previous Ages are researched, and that the player does not get any technology of the new Age unless it is free.

Each architecture set has a unique design for the Castle, and the civilizations introduced in the expansions for the Definitive Edition also have unique Castles.

Architecture sets[]

  • 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 Fénis 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 Castel Nuovo in Naples, Italy, but with decorative elements from the gates and round towers at Saladin's Cairo Citadel. The merlons are Moorish style, like those in the Almoravid Qubba.
  • 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.


  • The Indian/Dravidian Castle appears to be based on the Kumbhalgarh Fort in Rajasthan, though the official site claims inspiration from Golconda Fort in Hyderabad and fortresses in Karnataka.[1]
  • The Burgundian Castle is based on Flemish castles such as the Beersel Castle.
  • The Sicilian Castle is based on the Castello Ursino in Catania, Sicily.
  • The Bohemian Castle is based on the Karlštejn Castle.
  • The Polish Castle is based on the Będzin Castle.
  • The Bengali Castle is based on Lalbagh Fort.
  • The Gurjara Castle is based on the Gwalior Fort.
  • The Hindustani Castle seems to be a blend of elements from several of Delhi's castles (see gallery)
  • The Roman Castle is based on Roman Castrum forts.
  • The Armenian Castle is based on Yılankale Hill Fort (name in Turkish, in Armenian: Levonkla).
  • The Georgian Castle is based on Akhaltsikhe Castle.


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.
Age of Empires II manual


  • 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 hit point and armor upgrade for their Castles (Hoardings, Masonry, and Architecture), arguably giving them the worst Castles out of all civilizations. Fortunately, they do not rely as much on their unique unit as other civilizations.
  • The Huns have the most useless Castle, since both their unique technologies are very situational. Additionally, their Tarkans are also not very useful in most cases, and they can also be created at the Stables as need be. They also lack every Architecture and Hoardings, making their Castle extremely weak. As a result, the main usage for them is researching Conscription and making Trebuchets.
  • The Slavs with Detinets have the cheapest Castles in-game in terms of stone cost, needing 390 stone, while the Franks need 488 stone.
  • 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 occasionally 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 Hindustanis 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.
  • The achievement "Castle of Doubt" can be unlocked if the player loses an unfinished Castle that is at least 95% complete. This one is based on a popular meme highly known among the competitive scene as "Daut Castles", originating from a unsuccessful attempt to nearly complete construction of a castle made by Darko "Daut" Dautovic, a popular Age of Empires II player. It can be found on YouTube. Because of this, unfinished forward castles are widely called "Daut Castles".
  • In the alpha version, the Castles were bigger and cost more stone and wood.
  • Since Lords of the West, Castles of new civilizations have unique architecture for every civilization independent of the architecture set of other buildings, just like Wonders. Before this, only the Indians had a unique architecture set for their Castle, but due to having a unique architecture set in general.




  1. Starting in the HD Edition. 18-20 (and in some rare cases as low as 16, but never any lower than) in the original release. Oddly depends on a random number partially dependent on the civilization.[Citation Needed]
