Age of Empires Series Wiki

Provides military improvements.
—In-game description

The Arsenal is a military building in Age of Empires III that is available upon reaching the Fortress Age, or the Commerce Age when the "Advanced Arsenal" Home City Card is sent. It provides technologies to improve the effectiveness of military units from the three major lines – infantry, cavalry, and artillery.


Whether players build one or a mix of unit lines, the bonuses provided in the Arsenal can give their armies an edge.

The "Advanced Arsenal" Home City Card provides the Arsenal with additional, advanced technologies.

Civilization differences[]

  • Both the Haudenosaunee and Lakota have the "New Ways" Home City Card which gives them access to certain Arsenal technologies at the Longhouse and Teepee, respectively.
  • The Japanese can build one (and only one) Arsenal by allying with the Dutch at the Consulate, allowing them to ship an Arsenal Wagon. The Japanese Arsenal have all basic Arsenal technologies, while their Golden Pavilion wonder have Flint Lock, Paper Cartridge, Pillage, and Professional Gunners.
  • The Swedes have access to advanced Arsenal technologies (Flint Lock, Paper Cartridge, Military Drummers, Pillage, Professional Gunners, and Trunion) at all times, but do not have the "Advanced Arsenal" card.
  • The Hausa can get one Arsenal Builder (and retrain from the Town Center if it or the Arsenal are destroyed) by choosing the British alliance to advance into the Imperial Age. The Ethiopians can also get one Arsenal Builder (and retrain from the Town Center if it or the Arsenal are destroyed) by choosing the Portuguese alliance to age up.

  • The Arsenal built by the Japanese by allying with the Dutch at the Consulate now has the Dutch appearances through the Ages.


An arsenal is a storehouse for all manner of weapons and ordinance of war. Some arsenals were brick-and-mortar storehouses, guarded and protected. During the lead up to the American Revolutionary War, arsenals could be any stockpile of weapons, often hidden in attics and walls so that British soldiers could not find them. Artillery pieces were even taken apart and buried in fields to hide them, making "arsenals" out of entire towns.

On April 19, 1775, the British marched into Lexington hoping to chase down rebellion leaders and capture an insurgent arsenal. The British regulars outnumbered the revolutionaries 10 to 1 and ordered the gathered militia to stand down so that they could go about disbanding the militia and seizing or destroying any weapons cached in an arsenal.
