“	Upgrade of the Sentry Tower. The Guard Tower has more hit points, attack strength and range.	”
—In-game description in the Definitive Edition

The Guard Tower is a tower in Age of Empires, the upgrade to the Sentry Tower available in the Iron Age.

The infobox uses "O" as the shorthand of "original" for the original icon. Moreover, it uses the following shorthands for different architecture sets:

• G - Greek
• A - East Asian
• E - Egyptian
• M - Mesopotamian
• R - Roman

Gameplay

To research its upgrade technology at the Granary, 300 food, 100 stone is required. This defensive building has 240 hit points, 6 attack, and 7 range and can be upgraded. It offers effective defense against Bronze Age units, but needs to be upgraded to the Ballista Tower to have any kind of effectiveness against Iron Age units. Almost every civilization can build this type of tower. The only exceptions to this are the Romans, the Minoans, and the Yamato.

Since Return of Rome, like all towers, Guard Towers can also be used to shelter up to five Villagers when the base is under attack. These garrisoned Villagers do not increase its combat power. No other unit can be garrisoned in towers.

Like all towers, Guard Towers are more resistant against stone throwing siege weapons than other buildings, having 18 additional armor against them (meaning they will do 10 bonus damage instead of 28).

History

“	The tower discovered on the wall at the ancient site of Jericho served several purposes. It extended the visual range of lookouts that would be watching for the approach of raiders and other visitors. An early warning might have been the difference between a successful defense and the fall of the town. The tower was a superior firing position for archery. Bowmen shooting down had an advantage in range and penetration power of arrows versus enemies shooting up. Enemies hiding at the bottom of the wall may have remained visible to archers in the tower. The tower itself was an independent bastion that could serve as the defensive position of last resort if the wall was carried. The Guard Tower was a superior fortification, well- designed for holding out against attack and for bringing weapons to bear on an attacker.	”
