Seven looks to Strip The City

Sydney it’s one of Australia’s most popular cities and tomorrow night  Seven will air a special looking at it’s building and how they were made.

Sydney is a city bursting at the seams. How did Sydney come to thrive in such an inhospitable place? Look beneath the city’s skin to discover the secret engineering wonders that make it possible and the geological forces that sculpted it. The city’s leading engineers and geologists reveal the secrets hidden inside Sydney’s buildings and beneath its streets that allow the city to function, from the concealed contours of the harbour that allow super size ships to sail into the heart of the city to the underground caverns that store its water.

7:30pm Wednesday   on Seven.
