Strip The City uses stunning CGI animation and expedition - driven actuality to strip major cities naked of their steel, concrete, air, ocean and bedrock - layer by layer, act by act - to explore their hidden infrastructure and solve key mysteries surrounding their origins, geology, archaeology, industry, weather and engineering. Each episode will explore six iconic features of each city - one per act. Each icon will take us a layer deeper into the city. They will range from man - made skyscrapers and metro systems to natural dunes and lakes.
