Cannon Making

Cannon Making is a form of Technology and Culture.

Description
Cannons may be made of bronze or even wood, but most are made of iron. The barrel must be exceedingly strong to withstand the blast of the gunpowder, and so must have an even thickness and no flaws. A barrel's strength may be enhanced by wrapping it in metal bands. Repeated hits from cannon balls will cause any masonry to quickly crumble, so cannon can quickly breach even the strongest city walls.
