The Battery Tower is a defensive building in Age of Empires III: Definitive Edition - Knights of the Mediterranean that can only be built by Battery Tower Wagons which are shipped once Königstein is researched at a Trading Post or Tambo placed on a House of Wettin palace.

Battery Towers are also capturable in the Balkan Mountains map.

• Researching Fortified Outpost, Fortified Blockhouse, Mighty War Hut, Mountain Castle, or Guard Tower grants Battery Towers a bombard attack, +50% hit points, and +100% anti-ship attack damage as well (also +5 Line of Sight by researching Guard Tower).
