The Keep is the second Tower-type building, automatically upgraded from Tower at the Medieval Age once Military 2 (Mercenaries) is researched. It is automatically upgraded to Stockade at the Enlightenment Age once Military 4 (Conscription) is researched.

When upgraded from the Tower, the Keep gains +250 hit points, +2 line of sight and +10 Metal plunder value.

For general information on Tower-type buildings, see Towers.

Trivia

• The Keep, unlike the majority of buildings, does not benefit from the Hit points bonus granted by Large and Major Cities.
• Since building models don't change in the Medieval Age, and the Keep upgrades in the Enlightenment Age, the Keep models only appear in the Gunpowder Age, being one of the only building models to be used for only a single age.
• After reaching the Enlightenment / Modern Ages, the Keep would automatically use the Stockade / Bunker models, even if the required Military technology was not researched yet. However, such a change would only be visual, as the name and the stats of the building would remain unchanged (except for Romans, whose Tower-type structures would actually upgrade without meeting their standard Military research prerequisites, which is granted by the undocumented feature of the Power of Caesar).
