Tower

Towers are a relatively inexpensive static point defence that automatically attacks enemies and protects units. Unlike many other buildings, you can build as many towers as you desire within your own borders.
All players start the game constructing a stockade during the Colonial Era. This building subsequently is automatically to a bastion in the Imperial Era. The stockade has a fire rocket attack, while the bastion has a shell attack.
While not a tower per se, a secondary defence is the Martello Tower. Martello Towers are bigger and better than normal wooden stockades, garrison more units, can garrison artillery, and are substantially more powerful than blockhouses - they have the ability to fire down on artillery, but suffer from having a minimum range and a high pricetag.
Towers can be garrisoned with troops to protect and heal them, as well as boost the building's offensive capability. Note, however, that some units cannot be garrisoned in towers: siege weapons can only be placed in cities and Martello towers, while tanks, tankettes and armoured cars cannot garrison buildings and can only be healed in certain situations. Equally, neither the bastion nor Martello tower is capable of targeting air units.
==Structures==
*Stocakde and Martello Tower - a cheap but powerful cannon-based defence that can be garrisoned but must be built within your borders, armed with light cannon. Last upgrade requires Trace Italienne.
*Blockhouse and Bastion, like the house, but can't be garrisoned, these buildings function primarily as light point defences that can be constructed outside your territory. This pairing requires the Attrition line.

==Notes==
In the long run, Towers and Castles are ultimately useless, particularly against artillery and ships.
=== The Southeastern Dragon ===
For this mod, Blockhouses and Tower swap attack parameters: 
* Tower: basic building that upgrades to the Stockade, attack reduced from 12 to 10.
* Blockhouse: attack parameter buffed from 10 to 12.
