"The Observation Post is the Gunpowder Age upgrade of the Lookout and serves the same purpose: It lifts the fog of war within a reasonable long range, making it an important early warning system. It also detects invisible units (such as Spies) within its line of sight. Note, that the building's line of sight does not increase with the upgrade - instead, it increases with each level of File:Science.png Science technology researched by +3 tiles."@en . . "170"^^ .

"The Observation Post is the Gunpowder Age upgrade of the Lookout and serves the same purpose: It lifts the fog of war within a reasonable long range, making it an important early warning system. It also detects invisible units (such as Spies) within its line of sight. Compared to the Lookout, it comes with an additional 40 hit points and a significant increase in building cost, while all other stats remain the same: It is still a fragile structure as it has no armor and cannot attack ground units. It does have the ability to attack enemy air units by shooting arrows at them, however, it's the same fairly weak, low-ranged attack it's predecessor has. Note, that the building's line of sight does not increase with the upgrade - instead, it increases with each level of File:Science.png Science technology researched by +3 tiles. In the Industrial Age all Observation Posts automatically upgrade to Air Defense Guns immediately and for free. This greatly improves their ability to combat the upcoming aircraft while retaining their surveillance functionality."@en .
