England is very close to Europe’s mainland: The Channel Tunnel, also playfully known as the ‘Chunnel’, connects Folkestone to Calais. The tunnel offers easy access between England and France and stretches over 31.5 miles. The tunnel was built in 1993, with the Eurostar’s handy services beginning in 1994. It’s the longest undersea tunnel in the world, with 23.5 miles of tunnel stretching 75 metres below the surface of the English Channel. Thanks to the Chunnel, you can get to Paris from London in just over two and a half hours!
