This article is about the technology in Age of Empires II. For the technology in Age of Mythology, see Masons.

Masonry is a technology in Age of Empires II available at the University. Once researched, it strengthens all buildings (except walls, Gates, Farms and Fish Traps) by providing +10% hit points, +1 melee armor, +1 pierce armor, and +3 building armor, making every building stronger, particularly against attacks from infantry and cavalry units.

Note that building armor does not protect against all kinds of bonus damage against buildings, it reduces the bonus damage from siege weapons, ships, Villagers, Tarkans, Battle Elephants, and War Elephants, but not from infantry units, foot archers, or Camel Riders.

Masonry is available to all civilizations except for the Aztecs, Byzantines, and Vietnamese. The Byzantines, however, have building hit point bonuses that increase with each Age, mostly compensating for their inability to research Masonry or Architecture.

Architecture is the further upgrade of this technology.

Definitive Edition[]

Lords of the West[]


Europeans of the Dark Ages and later had to relearn the techniques of masonry exhibited by the Roman ruins that surrounded them. Roman bridges and aqueducts stood for many centuries after the Roman Empire was gone, but the barbarian immigrants could not repair or duplicate these structures. The craft of masonry was gradually reclaimed and then advanced. The great achievements of European masonry in the Middle Ages were the cathedrals that appeared across the region.
