Mysterious tunnels built by King Ferdinand II of Bourbon snake underground in central Naples. These intriguing passageways were designed as an escape route for the king in 1853 before serving as a military hospital and bomb shelter in WWII and finally as a warehouse for impounded vehicles in the 1940s, 1950s and 1960s. The dusty aqueducts were recently rediscovered and now visitors can take a spell-binding tour of the tunnels encountering abandoned vintage motorbikes and cars along the way.

The Wanda Reign on the Bund hotel in Shanghai, China, took more than three years to build. The 20-storey building combines art deco style and early 20th century Chinese design.

Railroad to nowhere: Fascinating pictures reveal an abandoned Soviet JET TRAIN that was once capable of travelling at 160mph
These fascinating pictures show a Soviet ‘turbojet railcar’, which was built in the 1970s and proved capable of reaching an astonishing 160mph, thanks to the huge jet engines on its roof. What made this concept impractical was the extremely high fuel consumption. And so this power car was pushed into a siding and left to rot.
Off-limits to tourists: From Bolivia's 'death road' to ancient villages in Yemen, a peek inside beautiful places travellers DON'T visit
While much of the world is the modern traveller's oyster, there are regions you can't roam freely. Whether that be the mysterious lands of North Korea or Syria, currently in the throes of war. But in many of these places, extraordinary beauty lurks behind the tightly-drawn curtains, along with the promise that some day they'll be free to explore again. With a few exceptions, all the magnificent destinations showcased here fall under the FOC's red zone - areas where 'all travel' is expressly advised against. Said notable exceptions include Norway's Domesday Vault (inset), a heavily guarded cavern built under the Arctic snow which contains seeds from almost every nation on earth to be retrieved in the case of an global catastrophe. Good luck getting a peek in there. Pictured clockwise from top left: Congo's beautiful region of Likouala, Bolivia's 'Death Road', the Karakoram highway that links China with Pakistan and Yemen.

The color of money! From ancient kings to glimmering bird holograms, the most beautiful banknotes in the world revealed
There's a certain small pleasure to be had in examining the first bank note you are handed in a foreign country.

Here, MailOnline Travel has hunted out some of the most colourful and exotic notes that are - or were once - in distribution around the world.

'Mouldy sun beds, slime in the pool and closed restaurants': Father slams 'shambolic' all-inclusive family hotel for Fawlty Towers-style horrors
Nurse Tim Sheppard booked a week's trip to the Aquis Sandy Beach Resort in Corfu for the half term holiday with his partner Hayley Palk (inset, with Tim), and his two children Eloise, seven, and Amber, five. He described the resort as the hotel from hell - with most of the nine bars and restaurants closed. The family claim that their trip featured mouldy sun beds (bottom right); green slime in the swimming pool; broken drains; a litter strewn beach (top right and bottom left); rubbish stacked in corridors; a cracked and splintered entertainment stage; and dirty water at the buffet.

Now THAT’S mist-ifying: Incredible footage shows planes landing at London’s Gatwick airport despite dense fog
According to the filmmaker visibility was so poor at the London airport that some planes were actually forced to circle before landing or divert to another airport. The video has been viewed over 25,000 times online, with many impressed by the filming and the skill of the pilots. According to Plane Clever, by Christopher Bartlett, modern airliners can ‘land virtually automatically in fog’, but the air traffic controllers will space the aircraft out more as they land and depart.

Why the hotel of the future could be an eco-pod robot 'jellyfish' with 'tentacles' that catch trash and clean polluted water
Conceived by Janine Hung, a graduate architect based in the Philippines, the floating lodges (pictured) boast kitchen and bathroom-equipped living quarters and gardens in their underbelly that can raise fish and grow vegetables. Beneath the surface, the solar-powered structure has 'tentacles' (inset) which capture and collect rubbish, and filter polluted water - either storing it for human use or returning it to its source clean.
Pictured: The incredible submerged plaza you have to walk into the sea to reach (no wonder the design is based on submarines)
A futuristic-looking plaza will be transforming the Florida waterfront from 2018 and to reach it, you have to walk into the sea. But fortunately, you won't get wet as the whole complex will be set on a floating base that's inspired by the technology used on submarines. Currie Park (main) will occupy a 19-hectare vacant area off the coast of Lake Worth Lagoon in West Palm Beach. As well as featuring restaurants (right inset) and shopping areas (left inset), the huge complex will also have events at the auditorium and a circular pool that overlooks the sea.

It was a blast while it lasted: Last ever KLM 747 to buzz the beach at St Maarten touches down
One of the best things about Maho Beach, for many, on the Caribbean island of St Maarten-St Martin was seeing KLM’s 747s roar overhead to the airport nearby. But the last ever hair-raising landing by a jumbo belonging to the carrier was made on Friday. Many aviation fans took to Twitter to mourn the end of the era. User Maliniak said: 'Maho Beach without [the] KLM 747 will never be the same.' Kazi Ahmed wrote: 'Avgeek or not the magnificent KLM 747 at St Maarten airport was a sight to see.
