The <a href=https://www.ice.org.uk/what-is-civil-engineering/what-do-civil-engineers-do/the-channel-tunnel>Channel Tunnel</a> (or ‘Eurotunnel’, or ‘chunnel’, even) opened in 1994 and has been carrying passengers back and forth between the UK and Europe ever since then. With trains travelling out of London from St Pancras Station, onwards to destinations such as Paris, Brussels, and Lyon, it is an engineering and transportation success, with some people even using the tunnel to commute.

Prices can be found as low as £25 one way if travelling as a group, or from £29 as a single person, which represents excellent value for money. The trip to Paris takes just 2 hours and 15 minutes, leaving enough time for work or relaxation, reading a book or playing sudoku (which you can <a href=https://play.google.com/store/apps/details?id=com.easybrain.sudoku.android>download here</a>) en route.

Certainly the Eurotunnel is a vast improvement on the choppy, overly-long ferry journeys we used to make. It is one of the greatest achievements of our European alliance, perhaps.

The greatest feats of architectural engineering are situated all over the world. They do not belong to any particular nation, or to any one style or school of thought. What unites them is their imaginative scope and the enormous skill it has taken to bring them into being. Modern examples include the Hoover Dam, the <a href='https://www.marineinsight.com/maritime-history/a-brief-history-of-the-suez-canal/'>Suez Canal</a>, and the Channel Tunnel. Ancient examples abound, too, for instance the pyramids at Giza, in Egypt, and the Great Wall of China, which can be seen from space.

These older creations have withstood the centuries to be with us today, and they were made at a time when electricity and machinery did not exist. Therefore, they were created by hand. This makes them even more of an architectural wonder. The imaginations of engineers and architects, in combination with the hard work of numerous human beings, have literally resculpted the face of the earth.
