城市

一座城市地产

城市（英文：City） are holdings commonly held by republic rulers. They pay the most taxes, and once upgraded give numerous levies, but have a lower fort level than castles and their levies consist more of the lighter soldier types than both castles and temples.

Most characters cannot hold a city within their direct demesne without suffering penalties to taxes, vassal opinion, and levies. Government types that allows for cities in their direct demesne without penalty are merchant republics, Confucian Bureaucracy, Chinese and Roman Imperial; for Roman Imperial, the culture of the county where the city is located must be the same as the one of the character holding it.

Cities are worth more when built in a coastal county, as this allows two types of income-increasing buildings to be built and upgraded. Also, patricians of merchant republics can build trade posts in coastal counties, which boosts the income of cities in the county. Rulers of counties on the Silk Road can also build trade posts.

The buildings that can be upgraded in cities focus exclusively on light infantry, archers, and pikemen, as well as increasing income and tech research speed.

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

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

Note that building upgrades stack.

Fortifications

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.

City Fortifications I	50	182	+0.4 fort level	Town Walls I

Walls

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

Militia Training Grounds

Militia Training Grounds are one of the most important buildings in cities. They increase percentage-wise the total number of base troops provided by other buildings, which means more levies and garrisoning troops.

	Price (gold)	Build time (days)	Effects	Requirements	Tech Requirements
Militia Training Grounds I	150	547	+5% levy size +5% garrison size

Mustering Grounds

Mustering Grounds increase the raw number of light infantry and archers available. These two troops are of low quality, but make up the majority of armies and are utilised mostly in the skirmish phase of battles.

	Price (gold)	Build time (days)	Effects	Requirements	Tech Requirements
Mustering Ground I	100	365	+60 light infantry +30 archers

Economic Buildings

These economic buildings increase the income of the holding, a portion of which goes to the liege. These are good to build because whatever gold which doesn't go to the liege goes to the mayor of the city, who, in theory, will use that gold to build other buildings. If you are a patrician or a doge holding cities, constructing these buildings is a high priority.

Ports

Ports are buildings that can only be built in provinces with a coastline that provide extra income. If the player is holding coastal cities, constructing these buildings is recommended, more so if they also control the trade post in the same county.
