Radio
None
Allows a city to produce veteran air units (including helicopters). Also, damaged air units (again, including helicopters) which stay in town for one full turn without moving are completely restored.

Two cities with Airports can airlift one unit per turn. Airlifting instantly transports the unit from one city to another and will use all of the unit's movement points. A unit must have some movement points left to be airlifted.

Requires knowledge of the technology Radio.

B.barracks iBarracks 30
1
Gunpowder With a Barracks, each new land unit built in a city will automatically have Veteran status, which means that its attack and defense strengths are increased by 50%. Also, damaged land units which stay in town for one full turn without moving are completely restored.
  • The discovery of Gunpowder will make Barracks obsolete.
B.barracks iiBarracks II 30

Requires knowledge of the technology Miniaturization. Requires Oceanic terrain on the tile or an adjacent tile.

B.palacePalace 70
0
Masonry
None
Makes a city the capital and the center of your government. Corruption in other cities is related to how far away from the capital they are, except when the government is Democracy or Communism. On top of this, corruption in your capital itself is half of what it would otherwise be (as if it had a Courthouse).

The cost to enemy Diplomats and Spies of inciting a revolt in a city also depends upon the city's distance from the capital (under all forms of government). Your capital city itself cannot be incited to revolt, and enjoys a bonus when enemy agents try to evade your own agents stationed in the city, or sabotage your buildings.

Take good care of your capital, as its loss may result in your empire plunging into civil war. Losing your current palace also results in losing whatever spaceship you might have.

Under Despotism the city containing the palace gains a +75% production bonus, and under Monarchy a +50% production bonus.

Requires knowledge of the technology Masonry.

  • A 'small wonder': at most one of your cities may possess this improvement.
  • All players start with this improvement in their first city.
  • If you lose the city containing this improvement, it will be rebuilt for free in another of your cities (if the 'savepalace' server setting is enabled).
