About Walls

Priority: Medium

Walls provide passive defence for your city, reducing the damage enemy attacks deal to your troops during sieges. Higher Wall levels increase your city's defence rating and can turn a losing defence into a draw or victory.

Upgrade Tips

1Walls are especially valuable if your Sanctuary is shielded — they provide the last line of active defence.
2Upgrade Walls when you're preparing for an Alliance war to protect your resource buildings.
3Walls don't need to match your Sanctuary level exactly, but keeping them within 5 levels is recommended.
