Template:AoEIIBuildingNoBuildThe Sea Gate is an unconstructable defensive structure in Age of Empires II: The Conquerors. It allows passage through Sea Walls. Sea Gates are the only structures that cannot be found in the Scenario Editor. They make two campaign appearances, however. In Walls of Constantinople and Fall of Rome they are included in defensive structures that fortify enemy harbors.
