"Powerful fortification that produces unique units and Trebuchets. Available from Castle Age, it is both a formidable defensive structure and a production building."
Strategic Analysis
Strategic Role
The Castle is the pinnacle of medieval fortification. It fires powerful arrows, produces your civilization's unique unit, and can hold an entire army in garrison. A well-placed Castle can single-handedly control an area of the map.
Key Tactics
Defensive Castles
Place Castles at choke points or near your Town Centers. A Castle covering your main gold can make your economy nearly unraidable.
Forward Castles (Castle Drop)
Build a Castle aggressively near the enemy base to pressure their economy. This risky play can win games if executed correctly.
Trebuchet Production
Trebuchets are the only units that can safely destroy enemy Castles. Always have Trebuchets ready for late-game siege.
Unique Unit Mass
Your civilization's unique unit is often extremely powerful. Multiple Castles enable mass production of these game-changing units.
Warning
Castles require 650 stone. Secure stone mines early and consider buying stone from the Market if needed.
Stats Analysis
The Castle is the most powerful building in the game with 4800 HP, high armor, and devastating arrow fire. A fully garrisoned Castle can repel most attacks.
Hit Points
4800 HP
Massive health pool. Only Trebuchets, Bombard Cannons, and massed siege can take down a Castle efficiently.
Arrow Damage
11 Base
Castle arrows deal 11 damage with +9 bonus vs rams and +0 vs buildings. Additional garrisoned units add more arrows.
Garrison Capacity
20 Units
Can shelter 20 units. Each additional unit beyond 5 adds another arrow, up to 20 total arrows.
Line of Sight
11 Tiles
Excellent vision range. Castles provide great map awareness and can spot incoming attacks early.
Stone Cost
650 Stone
Very expensive. Plan your stone economy carefully to afford Castles.
Technologies
Placement Tip
Place Castles to cover key resources, choke points, or your production area. In 1v1, a single well-placed Castle can win the game.
Timing Tip
Build your first Castle upon reaching Castle Age if you have enough stone. Prioritize Castle placement over additional Town Centers if you're under pressure.

Context & meta
The Castle is the pivot of the Castle Age: 650 stone and 200 seconds of construction for 4800 HP, a garrison that adds arrows, and the only building that trains a civilization's unique unit and researches both of its unique technologies. It also produces Trebuchets and Petards. Placed forward, within reach of an opponent's economy, it converts stone into map control and forces an answer; placed at home, it is what an army retreats behind. The cost is exclusive: the stone that pays for a Castle is the stone that would have paid for Town Centers, and that arbitration is most of the decision.
History & balance
The Castle is the heaviest commitment the game offers outside an age-up: 650 stone and 200 seconds of construction for 4800 HP. Its design makes that price do three separate jobs — it garrisons and shoots, it produces the civilisation's unique unit, and it researches both unique technologies — so a civilisation whose identity sits in its unique unit cannot express that identity without spending stone first. That is also what makes a forward Castle a strategy rather than a stunt: the building is not a wall, it is a production centre placed where the fighting is. The stone it costs is the same stone that would have bought Town Centers, and that trade is the whole decision.
In pro play
A Castle costs 650 stone and 200 seconds of building time, so it is never a casual purchase: it either protects something that matters or threatens something that matters. Built forward, it takes map control and forces an answer; built at home, its 4800 HP and its garrison make it the anchor an army retreats to. Place it where units already fight rather than where the map looks empty, and remember that stone spent here is stone not spent on Town Centers. It is also the only building that produces unique units and researches both unique technologies, so a civilization that lives on its unique unit lives on its Castles.
How to counter it
Trebuchets are the canonical Castle counter — they outrange the Castle's 11-tile arrow range with their 16-tile attack range. Two Trebuchets safely break a Castle in ~90 seconds. Bombard Cannons (12-range) work but require Chemistry. Petards detonate Castles with 175 damage per Petard — 25 Petards delete a fully-garrisoned Castle in one volley. The macro counter to forward-Castle aggression: contest the opponent's stone mining before they have 650 stone. Stone harassment (raiding the stone gathering point) often prevents the Castle from being built at all.
