The Watchtower is a special building upgrade available only on Annual Special servers.
It enhances a city’s defensive strength and can be built only inside cities, not villages.
Requirements
- A city (see: Special Servers – Cities) 
- Any type of wall (Teutonic, Roman, Gaulic, etc.) 
Overview
Watchtowers act as an improvement to walls, not a separate structure.
They grant an additional defensive bonus to all defending troops in the city and also increase population without increasing crop consumption.
Key details:
- Can be built only in cities (not villages). 
- Upgradable up to level 20, regardless of the wall’s level. 
- Each level grants a +1% flat defense bonus to all defending units. - For example: - Level 10 = +10% defence 
- Level 20 = +20% defence 
 
 
- The Watchtower bonus is added separately to the wall bonus (they do not multiply). 
Durability and Destruction
- Watchtowers cannot be directly targeted by rams or catapults. 
- However, if the wall is destroyed, the Watchtower is destroyed as well. 
- Rebuilding the wall automatically restores the ability to rebuild or upgrade the Watchtower.
