Castle

A castle is a fortified structure or private fortified residence for control of the lands around it. Castles served a range of purposes, the most important of which were military, administrative, and domestic. As well as defensive structures, castles were also offensive tools which could be used as a base of operations in enemy territory. Castles are usually controlled by nobles.

Improvements

Barracks

Castle Fortifications
Castle fortifications are set of defensive structures that protect the city from besiegers and raiders. These structures can store supplies or make sieging more difficult for the attacking force.

Walls
Walls are erect structures surrounding the city to defend from the attackers. Larger walls require more soldiers to man it, increasing the number of soldiers you can raise from the city. Due to the security of the walls provided, the city mayor can slightly increase the taxes in the city.

Districts
The social hierarchy is clearly defined by the districts. There are three notable social classes in the city.

Nobility
The nobility are the most elegant and rich people in the settlement. They are privileged enough to have their own personal bodyguard, own a set of heavy equipment, and minor political power in the local politics. They are the usual bodyguards of the barons due to their equipment.

Citizens
Merchants, tradesmen, and citizens live in the citizen districts. Most of the commerce are made by the citizens; they are wealthy enough to do some investments and trading. Most of them are happy most of the time. They can train in the castle's army and have a decent equipment for it.

Commons
The commons consists of the farmers, serfs, and slaves. They enjoy some form of security from the castle, but they usually complain of taxes they need to pay for it. They consist of the majority of the population, doing all the work to keep the castle bustling and alive. The commons can be said to be the backbone of the castle economy, and can be raised to the castle's garrison if needed.
