Construction resources

Foundry

Produces Iron for City construction and protects a portion of it from enemy looting.

By ClanOps · Updated 14 September 2026

Overview

The Foundry produces Iron, one of the resources used to construct and upgrade buildings and rebuild damaged Walls.

Build more resource-producing buildings and upgrade them to increase your City’s output. Higher levels increase hourly Iron production.

The building protects a portion of your Iron from enemies. Upgrading it increases this protected amount.

Compare hourly production and protected Iron at each building level.
