Research condition
Available to Africans from the Fortress Age. Research it at Wall, Church (Ethiopians), Mosque (Hausa), Mountain Monastery, or University.
When to research
Prepare the affected buildings or positions before researching City Walls: Wall hit points +600%, but build time +80%. The benefit matters only while those structures are part of the plan and can be protected; keep troops available to hold the area. Use the Wall, Church (Ethiopians), Mosque (Hausa), Mountain Monastery, or University for research. Research takes 60 seconds and costs 1,200 Influence.
Durability comes with slower construction
City Walls increases wall hit points by 600% but also increases build time by 80%. The Fortress Age research costs 1,200 Influence and takes 60 seconds. The large durability gain suits a plan that needs a defended perimeter, but it is not immediate protection: begin before the attack window and retain troops to respond to siege.
A major health gain with a construction-time trade-off
City Walls increases Wall hit points by 600%, while also increasing wall build time by 80%. The Fortress Age research takes 60 seconds and costs 1,200 Influence. The stronger perimeter can delay a siege, but the slower construction means it should be researched before the attack window; beginning the upgrade after an enemy reaches the base may leave the player with unfinished defenses. The bonus applies to Walls, not to units or every defensive building.
Civilization-specific research sites
African civilization access is listed through a Wall, Mountain Monastery or University, with Churches for Ethiopians and Mosques for Hausa. Confirm the correct site and Influence supply before planning the upgrade. A stronger wall buys time rather than winning the fight by itself: retain an army that can respond to artillery or defend another approach, and avoid investing in a long perimeter that the economy cannot finish or protect.
