Wall hitpoints increased.
—In-game description

Bastion is a technology in Age of Empires III that can be researched once the Colonial Age is reached at a Wall, while European civilizations can also research it at the Church (Mosque for the Ottomans). Once researched, all Walls get +150% hit points.

Bastion is available to all civilizations except for the Sioux, who cannot build walls in the first place. With the release of the Definitive Edition, the Lakota can build Walls from the Industrial Age, so Bastion is only available to them from that age.
