Watchtower
An upgrade to a city's wall on Annual Special servers, not a building of its own. Each level adds a flat defence bonus for every unit defending the city, on top of the wall's. Rams and catapults cannot target it, but it falls with the wall.
Build times at x1 with a level 1 Main Building, which takes 100% of the base time. Click a row to start a range and another to end it.

The Watchtower is an upgrade to the wall, available only in cities on the worlds that have them. It adds defence on top of whatever wall is already there.
- Cities only, and it needs a wall of any kind to sit on.
- It adds a flat 1% defence per level, separate from the wall's own bonus, and rises to level 20 independently of the wall's level.
- It cannot be targeted by catapults, but it falls with the wall if the wall is destroyed.
- It adds population without adding crop upkeep, which is unusual and makes it cheap to keep.
Strategy. Twenty per cent of flat defence, on a building nobody can aim at, for no crop. In a city worth defending it is close to free.
