The Channel Tunnel is one of the biggest engineering projects ever undertaken in the UK. Taking more than five years to complete, with more than 13,000 workers from England and France collaborating to realise the vision, the tunnel has been named one of the seven wonders of the modern world.

Today, as thousands of passengers take the Eurotunnel le Shuttle under the Channel every year, it can be easy to take for granted this extraordinary and unique man-made feat.
