Stichwort Infrastructure

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.

Following workers across the capital for three years as they race to build an enormous super sewer on time and on budget.

Hinkley Point C, in a remote corner of the Somerset countryside, will be one of the largest nuclear power stations in Europe, and the UK's first new station in a generation. The 22-billion-GBP project requires mammoth foundations for the two reactors, excavation of 3.5km cooling water tunnels under the Bristol Channel, and an airtight inner steel lining to contain any radioactive material in the event of a meltdown.

The Channel Tunnel stands as an engineering triumph and a testament to what can be achieved when two nations, Britain and France put aside their historic differences and work together. On the 25th anniversary of its opening, we reflect on what it took to build the longest undersea tunnel ever constructed.
