Ron Herron gave cities giant robotic legs so they could cross continents, dock with infrastructure and leave whenever their inhabitants wanted a different future.

What it was
A visionary mobile-city project created within the British architecture group Archigram.
Enormous self-contained structures would roam a post-apocalyptic landscape and connect temporarily to utilities, information and other walking settlements.
Existence timeline
Ron Herron imagines autonomous urban structures capable of movement.
Mechanical cities stride across land and sea in vivid perspective images.
The group circulates the proposal as radical paper architecture.
Walking City joins Archigram's wider critique of permanent buildings.
The group stops producing its magazine without constructing the city.
Original drawings enter architectural collections and exhibitions.
Why it ended
Walking City was paper architecture published to provoke debate, not a funded building programme, and no full-scale unit was attempted.
Last confirmed trace
Herron's collages and drawings survive in museum collections and the Archigram archive.
What it left behind
The project anticipated mobile networks, adaptive infrastructure and machine-like megastructures while becoming a defining image of 1960s radical architecture.
How we classified it
The proposed archive unit never reached ordinary public access in the form being documented.
The strongest verified milestone maps to documented_concept under Arrival Score V1.
