Walls

“Let them come. Stone does not flinch.”

Walls are massive fortifications encircling a city, transforming it from a vulnerable settlement into a defensible stronghold. Thick stone ramparts, watchtowers, and reinforced gates force attackers to commit vastly greater resources to any siege, buying precious time for defenders and deterring all but the most determined aggressors.

• +100% city defence bonus.

Strategy

Walls are a critical defensive investment for any city that faces a realistic threat of attack. The +100% defence bonus effectively doubles a city’s combat strength when defending, turning even a modest city into a formidable obstacle for invading armies. Prioritise Walls in border cities and any settlements within striking distance of aggressive neighbours. Interior cities can safely delay Walls in favour of economic buildings, but frontier cities should build them as soon as Masonry is researched. At 35 production and only 1 gold maintenance, Walls are remarkably cheap insurance against the catastrophic cost of losing a city.

Historical Background

City walls rank among humanity’s oldest monumental construction projects. The walls of Jericho, dating to approximately 8000 BCE, are among the earliest known examples, featuring a stone wall over three metres high backed by a massive tower. The fortifications of ancient cities grew increasingly sophisticated over millennia – from the Cyclopean walls of Mycenae to the triple walls of Constantinople, whose Theodosian fortifications withstood sieges for over a thousand years before finally falling to Ottoman cannons in 1453. The advent of gunpowder artillery in the late medieval period rendered traditional vertical walls obsolete, leading to the development of low-profile star forts with angled bastions designed to deflect cannon fire, a revolution in military architecture pioneered by Italian engineers in the sixteenth century.
