Arras In France
An underground dwelling in Arras in France has been traced all the way back to the Middle Ages, and it is said that its tunnels may even have been used to mobilise supplies throughout the great wars that have followed since. A well known fact about this particular underground region is that the British helped to expand it during World War II in a bid to aid the war efforts against Germany at the time. Over 20 000 soldiers are said to have been living here in the midst of the Battle of Arras. If you’re curious about how it looks in person, make a stop at the Carrière Wellington museum in the area to see it for yourself.
Guanajuato In Mexico
Guanajuato is a well known city in Mexico, renowned for its colonial architecture, history and resilient structures. The city was founded in the 1500’s by the Spanish, who quickly realized that it was an area that could be mobilized into an abundant resource of silver through mining efforts. Directly below the city a series of underground tunnels and caverns can be found. These are relatively modern constructs, set up as a contingency plan for the high rate of population growth seen in the country in recent decades. Rather than expanding upwards, officials decided that going underground would be a viable alternative to consider.
