Kuchi Tunnels in Ho Chi Minh City
In terrifying, cramped manholes, not allowing to forget about the horrors of the Vietnam War, you can get to this day. Only this descent will require certain courage – underground tunnels, once filled with deadly traps, were used as the secret weapon of the Viet Cong and supply lines for the partisan army. Secret catacombs still remain a rather creepy place, and not every traveler dares to walk along these lifeless corridors.
Flooded corridors under Cape Town
The history of the winding system of underpasses goes back to the depths of the 17th century. Then the Dutch colonists were in dire need of freshwater and used underground tunnels as storm drains. Going to South Africa in the dry season today, you can wander through the ancient passages on your own or as part of an excursion group.
Abandoned Sydney Railway Tunnels
An unused network of tracks as the remainder of the previous era covers almost the entire territory of the Australian city. You will hardly believe that grass-covered platforms, rusted frames for advertising posters and dilapidated signs were not so long ago a part of the metropolis. In some places, lines lead underground to bomb shelters and bunkers. But the main secret attraction hiding under the St. James station is that it officially bears the name of St. James Lake, but in fact, it is a foul-smelling puddle 5 meters wide. The urban legend claims that it is here that the military conduct their training in the dark.
A little-known fact: the Russian capital is a tidbit for international researchers of the underground life of cities. Even VICE conducted its own investigation and told English-speaking readers about the existence of at least six levels of a complex system of tunnels and bunkers. But the secret of the Metro-2 project, built on the orders of Stalin, is considered the highlight of the mysterious catacombs. The authorities have not yet confirmed its reality, but, however, have not refuted it. Therefore, starting your journey through the tunnels under cities from around the world from Moscow, you can not only get practice in walking along with narrow manholes but, in the literal sense of the word, get to the bottom of the truth.
The second life of bomb shelters in London
Residents of London decided to use the bomb shelters built during the Second World War as an agricultural complex. The first to think of this was Zero Carbon Food. Salad, dill, radish, garlic, and other herbs are grown in special hydroponic greenhouses. Greenhouses work round the clock, and in the morning fresh crops are delivered to the shops and restaurants of the city.
