城堡

城堡地产（尽管有个特殊子建筑来模拟君士坦丁堡的著名城墙）

城堡（英文：Castle）地产主要由封建领主持有。它们相对城市和神殿来说税收较低，但提供更好更多的征召兵。城堡是大多数省份的首府；因此，其高于神殿和城市的要塞等级能够有效帮助省份抵御围攻与劫掠。

以下政体的角色能够在不受惩罚的情况下持有城堡：封建制、伊克塔制、僧侣封建制、商业共和国、儒家官僚制和中华帝国制。

Castles are composed of buildings which must be upgraded to increase fort level, levies, or income. In addition to the buildings below, castles are allowed to build culture-specific buildings depending upon the culture of the holding's owner. Note that castles are the only source of cavalry levies, and the only holding type where 文化建筑s and training grounds can be built.

Constructing a castle (or city) can prevent a formerly-normadic province from reverting due to nomad agitation.

Hindu characters must be of the caste before they can be granted castles.

Note that the effects of building upgrades stack.

城堡防御工事

These buildings increase fort level, increasing the time it takes an attacking army to siege the holding and reducing the amount of free loot available to raiders.

墙垣

Walls increase levy size and fort level, raising the defensive capacity. They also slightly increase yearly income from the holding.

主楼

Keeps are arguably the most important building for castles. They increase garrison size, thereby increasing the defensive capacity of the holding, and increase levies, giving the holder the ability to field more troops.

Name	Price	Build time	Effects	Requirements	Tech Requirements
Keep I	150 gold	547 days	+5% levy size +5% garrison size

Militia Training Grounds

Militia training grounds increase the output of light infantry and archers in a holding. Both are low quality troops, but tend to make up the majority of armies, being very numerous, and are two of the best troop types during the skirmish phase at the start of a battle.

Name	Price	Build time	Effects	Requirements	Tech Requirements
Militia Training Ground I	100 gold	365 days	+80 light infantry +10 archers
Militia Training Ground II	120 gold	547 days	+50 light infantry +50 archers	城堡墙垣 I Militia Training Ground I	Castle Infrastructure I
Militia Training Ground III	200 gold	1095 days	+20 light infantry +90 archers	Militia Training Ground II	Castle Infrastructure V
Militia Training Ground IV	300 gold	1095 days	+30 light infantry +120 archers	Militia Training Ground III	Castle Infrastructure VII

Training Grounds

Training grounds are one of the key buildings that make castles the best holding for levies. This upgrade gives increased morale to all levies raised from the holding, which can make the difference between routing the enemy and being routed. Additionally, the increased levy reinforcement rate means that losses will be replenished faster, and is key when fighting a defensive war. This building is also useful if you intend to form your own mercenary band.

Name	Price	Build time	Effects	Requirements	Tech Requirements
Training Grounds I	200 gold	730 days	+10% morale +10% levy reinforcement rate +20 retinue size	城堡墙垣 II

Training Grounds III	300 gold	2190 days	+20% morale +20% levy reinforcement rate +20 retinue size	Training Grounds II	Castle Infrastructure VI

Barracks

Barracks provide castles with heavy infantry and pikemen, which gives an army staying power and the ability to kill in the melee phase of combat.

Name	Price	Build time	Effects	Requirements	Tech Requirements
Barracks I	100 gold	365 days	+30 heavy infantry +15 pikemen
Barracks II	120 gold	547 days	+40 heavy infantry +15 pikemen	城堡墙垣 I Barracks I

Barracks VI	500 gold	2190 days	+65 heavy infantry +30 pikemen	Barracks V	Castle Infrastructure VII

Stables

Stables are another key to the power of castles. They are the only way outside of culture specific buildings to acquire heavy cavalry (the best troop type in the game) and provide lots of light cavalry, which is an all around useful troop type, and great for chasing down fleeing armies.

Name	Price	Build time	Effects	Requirements	Tech Requirements
Stables I	100 gold	365 days	+35 light cavalry

Castle towns are the economic upgrade for castles, and are thus extremely important.

文化建筑

主条目：文化建筑

文化建筑s and Steppe 文化建筑s can be built in castles, varying in name and specific contributions to their levy on the culture of the province the castle holding is in.

Beyond contributing levy forces, many 文化建筑s also give a bonus to the offence, defence, or morale levels of specific units. As these bonuses apply to the retinue of that character if these 文化建筑s are built in the capital castle holding, placement of the capital can impact the quality of the army.

All 文化建筑s, except for the Steppe 文化建筑s, have the same requirements.

	Price (gold)	Build time (days)	Requirements	Tech Requirements	Notes
文化建筑 I	200	730	城堡墙垣 II	防御工事 II	Benefits will vary depending on the culture of the province

文化建筑 IV	500	2190	文化建筑 III	Castle Infrastructure IV	Benefits will vary depending on the culture of the province

Steppe 文化建筑s exist for certain (steppe) cultures when building in steppe terrain, instead of the default 文化建筑s.
