# Strip the City

Strip the City is a documentary science television series that aired on the Science Channel in 2012 and 2014. It explores the construction of major cities and the geology lying beneath them, with an emphasis on computer-generated imagery to "strip" away layers of structures and the rock of geological features to reveal their interiors.

## Content

Strip the City uses computer-generated imagery (CGI) to "strip" major cities layer-by-layer of their steel, concrete, buildings, roads, rivers. and bedrock to reveal the technology and infrastructure that allowed their creation and keeps them functioning. CGI also peels back the layers of buildings to show they were constructed, strips away oceans to reveal sunken cities, and cuts into rock to display the inner workings of volcanoes, subterranean rivers, underground volcanoes and cliffs, fault lines, and ancient catacombs and describe their impact on life in the cities above them.
A later Science Channel series, Strip the Cosmos, built upon the CGI concepts introduced in Strip the City, employing them to reveal the interiors of astronomical objects.

| 1 | "Ancient City: Rome" | Roeland Doust | October 26, 2012 (2012-10-26) |
| Ancient Rome is the prototype of all modern cities, and 2,000 years ago it was the biggest city in the world, with a population of one million people. Roman engineers mastered the construction of buildings, roads, and viaducts and set the city on course to become the hub of the Roman Empire, the greatest Empire the world had ever seen. Known as the "Eternal City," Rome has survived better than any other ancient city on earth and now is home to three million people. The episode strips Rome's most famous landmarks bare to reveal how Roman engineers built the Pantheon, Colosseum, Trevi Fountain, and Appian Way; explores deep underground to reveal the crucial role volcanoes played in Rome’s growth; descends into the tunnels that run under most of Rome; abseils into an ancient aqueduct; and reveals how the Rome Metro is being built. It also explores the volcanic geology that shaped Rome’s past — providing the pozzolanic ash that is a key ingredient of Roman concrete and the lava that underpins Rome's roads — and challenges its future. ||||

Each winter temperatures in Toronto plummet to −40 °F (−40 °C) and strong snowstorms strike the city. The episode explores how Toronto grew into a great city with CGI animation that peels the glass and concrete off its skyscrapers to reveal their design and construction and sucks the water up out of its lakes to explore their origins; visits Toronto's leading engineers and geologists as they explain what keeps the iconic CN Tower standing, how Toronto's buildings are protected from snowstorms, and how the buildings keep their occupants warm in the extreme cold of winter; and explores the city's geology, from the rich salt reserves that power Toronto's industry to the colossal waterfalls that generate power for its expansion. ||||
| 6 | "Underground City: London" | Roeland Doust | November 30, 2012 (2012-11-30) |
| London is the world’s most extreme "underground city." As its buildings soar higher, its tunnels go deeper, and London has more underground infrastructure than any other city in the world. This episode joins people working underground in London, from tunnel builders digging a new London Underground line 40 metres (131 ft) beneath the ground to workers scrubbing its sewer tunnels to prevent outbreaks of disease; lifts up Buckingham Palace to reveal a "lost" river beneath it; and showcases the innovative engineering behind the construction of London’s new port, London Gateway. CGI animation peels away the structure of the Tower of London layer by layer to reveal the true scale of the River Thames, which once was a tidal torrent, and strips the steel and glass from Europe’s tallest skyscraper — The Shard — to reveal its design. The episode also explores the geology that shaped the city’s past and challenges its future, from the rich clay that it sits on to the river that may one day consume it. ||||

| 7 | "Inca Empire: Machu Picchu" | Joe Myerscough | March 19, 2014 (2014-03-19) |
| Perched on slopes of the Andes at an elevation of 11,000 feet (3,350 m), the ancient city of Machu Picchu was home to over a thousand people. The city was built as a royal retreat for the Sapa Inca — the emperor — of the Inca Empire, and it took a thousand stonemasons almost a hundred years to complete it. Although constantly under threat from earthquakes, landslides, and floods. Machu Picchu has survived for over 400 years. The episode uses CGI animation to strip Machu Picchu's temples, buildings, and terraces to reveal the techniques that allowed the Inca to build the city without modern tools in one of the most inhospitable regions on earth and the stonework that made Inca roads one of the most advanced highway systems in the ancient world. Engineers and archaeologists explain how the Inca earthquake-proofed the walls of the city's structures with precision-cut granite blocks and built a sophisticated canal system which supplied water to the city throughout the year. The episode also explores the geology that shaped Machu Picchu’s past and challenges its future, from the steep granite slopes it is built on to the threat of deadly landslides. ||||
