Can a megacity be built, used, and erased in ten weeks?

Rahul Mehrotra: The architectural wonder of impermanent cities · 13:17 · Video: TED · Watch at the source

In short: Explore the architectural logic of the Kumbh Mela, a massive religious festival in India. This video examines how a fully functioning megacity can be assembled and disassembled in just two months, offering a blueprint for more adaptable, low-impact urban design.

Urban designer Rahul Mehrotra explores the Kumbh Mela as a model for "impermanent cities." Every 12 years, this temporary settlement springs up in India, featuring infrastructure that is completely dismantled in a single week after ten weeks of use.

The core idea is to move away from permanent, rigid urban structures toward cities that can travel, adapt, or disappear. This approach aims to create functional human habitats that leave the lightest possible environmental footprint on the planet.
