Stone Wall and Gate in Age of Empires II: Definitive Edition.
A Wall is a relatively inexpensive defensive structure used to keep enemy units out of a specific area, often made of wood or stone. Walls can be upgraded, respective to the civilization in use.
Walls are used in conjunction with a Gate which allows friendly units to pass through. Gates can be built in a section of wall if it is the correct size. The article lists both walls and their corresponding gates.
Each wall aesthetically represents its constituent material and/or the civilization by which it was built.
Age of Empires[]
Walls become available in the Tool Age and can be upgraded in further Ages. Gates were added in Return of Rome.

Since Return of Rome, the following unconstructable defensive structures can be found only in the Scenario Editor:
Civilizations[]
The Babylonians and Shang have superior walls compared to other civilizations; each civilization has their wall hit points increased by +60%. By comparison, the Carthaginians, Macedonians, Minoans, and Yamato have the weakest walls, as they lack the Fortified Wall upgrade.
Age of Empires II[]
A Palisade Wall, Stone Wall, and Fortified Wall, each with a Gate
Walls are available from the Dark Age. Palisade Walls are rather fragile and can help to buy time in the early game when an enemy army is arriving. Due to their low armor and hit points, they are practically useless in later stages of the game and are replaced by the much stronger Stone Wall, which is available in the Feudal Age. Without siege weapons, Stone Walls are very hard to penetrate, so they make a very good defense against raids. However, building multiple layers of Stone Walls has diminishing returns, as Capped and Siege Rams can destroy multiple layers at a time. They can be upgraded to Fortified Walls in the Castle Age.
Palisade Gates were added in The Forgotten.

Age of Mythology[]
Walls are available in the Archaic Age, but can be upgraded through the different Ages. Gates cannot be built directly like in Age of Empires II. Instead, walls are simply clicked on and selected to become a Gate, for a cost, provided that the wall section being converted has the correct length.
Civilizations[]
Between the first three civilizations, the Egyptians have the best walls. However, with The Titans, the Atlanteans have overtaken them. With Tale of the Dragon, the Atlanteans were overtaken by the Chinese. The Norse possess the worst walls, having only the Stone Wall upgrade. The Greeks and the Norse are the only cultures with a God-granted upgrade, Hera's Athenian Wall upgrade and Heimdall's Safeguard, respectively. With Safeguard, Norse walls match Greek walls in hit points (without Athenian Wall).
Age of Empires III[]
- Main article: Wall (Age of Empires III)
Walls in Age of Empires III work the same way as their Age of Mythology counterpart.
Age of Empires IV[]
There are three types of walls in Age of Empires IV. They exist independently from one another and are not upgrades of each other, unlike previous games. Gates can either be built on top of walls, or an unfinished wall can be turned into a gate blueprint at an additional cost.

The Great Wall Gatehouse is a special gate landmark available to the Chinese that must be built on top of a Stone Wall. The Byzantine Aqueduct is a special case, as it has the 'wall' unit type and follows similar placement mechanics, but is not intended to block enemy movement.
Wall mechanics[]
Walls in Age of Empires IV are placed differently than other buildings and have unique mechanics. Walls do not follow the grid system and can be dragged freeform across the map at any angle. They can be dragged and built over all static resources automatically. Building a wall across a Gold Mine, Stone Mine, Berries, or Trees, will completely block navigation so that the resource acts as part of the wall. Gap fillers (small walls that extend from wall end pieces) are built automatically to help clearly show what is and is not walled off.
Walls can also be connected to any other allied walls (including interconnections between Palisade and Stone Walls), but cannot be connected directly to other buildings. This means that they must completely surround a building to block access to units. Walls do not interact with influence areas, so they are not affected by any bonuses that may affect other buildings within the area.
All foot units, such as infantry and Villagers, can climb onto allied walls using a Stone Wall Gate or Tower, or if a piece of the wall has been destroyed. Enemy infantry can also get on top of Stone Walls using destroyed segments or Siege Towers, although they cannot use Gates or Stone Wall Towers to get down, and must use either the Siege Tower or a destroyed segment of wall. Units on walls take reduced damage, and ranged infantry have increased range.
