City walls of antiquity

01

Tiryns

Walls 17 metres thick at Tiryns conceal vaulted stone galleries within their mass — corridors carved not to defend but, ancient Greeks believed, to house the Cyclopes who built them.

02

Uruk

The walls Gilgamesh supposedly built to ring Uruk have been carbon-dated to 3000 BCE — making the oldest surviving epic's most personal boast a verifiable archaeological fact.

03

Hattusa

Hattusa's double walls included sphinx-flanked gates and a vaulted underground tunnel — not for escape but for ritual processions — built by a civilization that negotiated history's first surviving peace treaty.

04

Walls of Constantinople

Constantinople's triple Theodosian walls — outer wall, inner wall, and a 20-metre moat — held every attacker from 413 CE until Ottoman cannon breached them on a single night in May 1453.

05

Walls of Babylon

Herodotus ranked Babylon's walls among the world's wonders; excavations showed he undersold them — the outer wall ran 90 feet thick, wide enough to turn a four-horse chariot on top.

06

Carthage

Carthage's triple walls sheltered stables for 300 war elephants and 4,000 horses within their mass; Rome's demolition in 146 BCE was so absolute that archaeologists still argue over where the walls stood.

07

Regensburg

A Roman legionary fortress built around 179 CE forms the literal foundation of modern Regensburg — its stone walls, still standing to several metres, prop up the ground floors of inhabited apartment buildings.

08

Mycenae

The limestone blocks at Mycenae's walls weigh up to 6 tonnes each, fitted without mortar across a circuit that stood 900 years before the Greeks of Thucydides's era declared their ancestors could not have built it.

09

Buhen

Egypt's Buhen fortress, raised around 1860 BCE deep in Nubia, had a dry moat, brick battlements, and loopholed walls for archers — a complete medieval-style defense built 3,200 years before the Middle Ages.

10

Dura-Europos

When Sasanian forces breached Dura-Europos's walls around 256 CE, they buried the city in rubble — accidentally preserving inside the walls a synagogue, a Mithraeum, and the world's oldest surviving Christian church murals.
