Today, a journey across Russia's Trans-Siberian railway takes about a week. But exactly 100 years ago, upon its official completion, the trip took almost a month because the train trundled along at 20 miles an hour. Now the longest train line in the world, stretching more than 5,700 miles from Moscow to Vladivostok, the Trans-Siberian railway crosses two continents, 80 towns and cities, 16 large rivers and eight time zones. Here, MailOnline Travel takes a look back over a century of the Trans-Siberian's history with a series of fascinating pictures. Pictured (top right) an engineer in the region of Irkutsk during the 1960s, (centre) the railway cutting through the mountains in 1917, (top right) workers from a hard-labour camp on Sakhalin Island, who assisted on constructing the railway along the Ussuri River in 1890, (bottom right) laying of the tracks on the Eastern section, and (bottom right) a passenger train crosses the Devil's Bridge in Buryatia, Siberia, exact date unknown.

Earlier this year, MailOnline reported how Angela Nunez, a yoga teach from Middleburg, Virginia, gained over 10,000 followers on Instagram by sharing images of her horseback yoga poses (main).
Navigating your way at night can be tricky - especially when you're on two wheels. But now cyclists in Poland have been given a helping hand, thanks to glowing pathway. The high-tech track gleams at night, as the phosphor crystals it's made from emit light after being charged by the sun. Photographs show the path illuminated at night, glowing a vivid shade of blue. The luminous cycling strip is located in a park near the town of Lidzbark Warminski, in the north of Poland. It was created by the technology firm TPA Instytut Badań Technicznych Sp. z o.o. and is currently still in the testing faze.
So THAT’S why all the photographs are of the outside! Revealing the boring interiors of the Leaning Tower of Pisa after 300-stair hike to the top
The Leaning Tower of Pisa took 199 years to build. And it appears by the time builders reached the rafters they had run out of steam. Photos showing the tower's interiors reveal it as a hollow shell. It comes as a surprise to many, given the landmark's grand exterior, adorned with marble arches and intricate stone carvings. After climbing 300 stairs and paying a €15 entrance fee, visitors are greeted with bare bricks when they reach the bell tower.
Now THAT'S a tourist attraction that rocks: The incredible field of boulders that covers 720,000 square feet
Hickory Run State Park in Pennsylvania is home to a remarkable boulder field. The weight of the rocks is so great that the ground they've depressed the ground they sit on by 12 feet over the years. The surreal nature of the phenomenon is heightened by the fact that it's surrounded by lush evergreens. It's a bizarre, incongruous formation that draws in a steady stream of visitors, who often love to jump from rock to rock. Stunning drone footage (main shows a still from this) shows just how huge the field is.
Views to dine for! From the Empire State Building to the Colosseum, the restaurants with the best panoramas revealed
At some restaurants it's not just delicious food and highly quaffable wine that's on the menu. Some have views that are just as eye-catching as their dishes and drinks list. From The Rainbow Room in New York boasting a sublime panorama of the Empire State Building, to the Aroma in Rome looking over the floodlit Colosseum, there are dozens of settings to choose from. For city slickers, there are sky-high eateries looking down on the world below, and for those looking for something a bit more rural there are dinner tables looking out over the ocean or the African plains. In a bid to help you make the winning choice, MailOnline Travel has put together a directory of some of the best restaurant views in the world.
Would you rest in peace? The floating hotel that has a cinema, restaurants and a CEMETERY for up to 48,000 urns
The H.K. Ship Art Club is proposing the transformation of a 60,000 tonne cruise ship into a floating cemetery that will be stationed in Hong Kong and it will come with enough room for 48,000 funeral urns. But, extraordinarily, the vessel will also operate as a hotel and offer a range of services typically associated with cruises, including restaurants, gyms and even a cinema.

Andrew Studer, 20, from Portland, Oregon, has travelled the world to capture solo voyagers deep in the vast wilderness of places like Washington (top left), Oregon (top right and bottom left), and Iceland (bottom right and inset). With his photos, he is aiming to demonstrate the earth's prowess, and what 'small fish in a big, big pond' we are.
The rise of America’s entertainment capital: Exploring Las Vegas 60 years after Elvis first graced its stages
Once known as the land of kitsch, neon and 24-hour gambling, Las Vegas today is so much more. MailOnline Travel's Valerie Siebert found that 60 years after Elvis Presley (inset with Liberace) performed his very first residency in the city's New Frontier Hotel, Sin City is actually a place full of class that has less use for the likes of The King or, in fact, gambling than it ever has before. Pictured left is Vegas in 1953, just before Elvis' residency, and right is Vegas today - completely transformed.
Now THAT'S a copy cat! Bronze statue honors famed Istanbul feline Tombili - striking his favourite 'chilled out' pose
A rather plump cat who found fame after a photo of him 'chilling out' swept the web, has had a statue erected in his honor. Tombili from Istanbul, who passed away in August, was apparently known for lounging on the curb with his belly hanging out and his front paw up. And now, a statue has been installed in the feline's favourite spot, with his chilled-out pose captured for posterity. Many fans of Tombili have applauded the piece of art, while others are less keen on it.
Fantastic fjords and beautiful beaches: Breathtaking photos from Lonely Planet's immense new travel book that celebrates every country in the world
Lonely Planet's new edition of its voyage bible, The Travel Book, is extremely heavy - but that should come as no surprise, because it's laden with descriptions and facts for every country in the world and is stunningly furnished with more than 800 photographs. These spectacular images capture the unique essence of exotic travel destinations around the world. The book's odyssey starts in Afghanistan and circumnavigates the globe from A to Z, ending with Zimbabwe, and visiting every single country in between, from Norway's Geirangerfjord and Seven Sisters waterfall (top), to the seascapes of New Zealand (bottom left) and the mountains of Turkey (bottom right).
Inside 'the most haunted city in America': Take a tour of Savannah's spooky Historic District... in the back of a hearse
There are more dead people buried under the pavements of Savannah than there are living people walking on top. For all its pretty cobblestoned squares and antebellum townhouses, the exquisite seafood and Southern generosity, this small port on the frontier of Georgia and South Carolina has a dark underbelly: grisly tales of sordid murder, haunted houses and a colonial-era graveyard (inset) decorated with the lingering entrails of Spanish moss. Savannah could well claim to be America’s most haunted city. That’s why, this Thursday evening, I’m being driven round its deserted squares in the back of a hearse.
That rounds things off nicely! The thrilling moment a skydiver soars over a rare rainbow in the shape of a perfect circle
Anthony Killen, a Brit who was on his first skydive with an instructor over New Zealand's Bay of Islands, was 'laughing and ecstatic' when they spotted the technicolour spectrum. While actually witnessing this sight is a freak occurrence, the formation itself is not. All rainbows in their complete form are circular, we just can't see them from the ground, or from anywhere other than directly over them.
Former secret Chinese nuclear bunker that's the world's largest man-made cave at one MILLION square feet opens to the public
The 816 Nuclear Military Plant, located in the mountains of Fuling district in China's Chongqing municipality, was designed to manufacture plutonium in the 1960s, but never went into operation. It covers 1.1 million square feet, with more than 130 roads and tunnels (left) as well as educational light displays (top and bottom right).
Hidden treasures: Intrepid caver reveals stunning frozen sculptures lurking inside a towering European peak
Stretching from floor-to-ceiling these incredible ice stalactites look particularly eerie as they shine from the darkness and protrude from a cavern of red rock. The unusual frozen formations were captured by intrepid caver, Peter Gedei, at the Ivacic Cave hidden under the highest peak in Slovenia, Triglav. During his recent expedition, he also discovered a thick frozen bed of water which he said shone in 'beautiful colourful layers' when it was lit.
From the church so small its congregation sits outside to the chapel balanced half way down a cliff: Britain's tiniest - and loveliest - places of worship
A new book, Tiny Churches, by intrepid traveller Dixe Wills, explores the fascinating and varied histories of 60 of the country's most diminutive churches, from the church in Wiltshire so small the congregation sit outside to the chapel balanced halfway down a remote Pembrokeshire cliff. MailOnline Travel has rounded up a selection of some of the most beguiling churches featured in the book.
The stunning 'Stairway to Heaven' video of a luxury Swiss hotel's infinity pool that's made a HUGE splash on the internet... with more than 1.2m hits
Stepping into a steamy pool of water with the Swiss mountains visible in the cloudy twilight - this is the scene captured in a new video which has swiftly gone viral. Entitled Stairway to Heaven, the 39-second-long clip shows a woman getting into the infinity pool at the five-star Hotel Villa Honegg in Switzerland. The aquamarine waters seemingly have no end, as they run over an invisible edge to make way for sweeping views of the valley below. Towards the end of the video, a shot from high up reveals there is also a hot tub in the corner of the L-shaped pool.
Bats rule the roost when it comes to caves, ducking and diving through their dank dwellings. And now new drone footage attempts to mimic a bat's point of view, taking viewers inside the eerie Devetashka cave in Bulgaria that was inhabited as far back as 70,000 years ago, but is now home to around 30,000 bats. Footage captured by a YouTube channel reveals a giant cavern with large holes punctuating the length of it. At one point the camera steadily hovers along a dirt walkway. The lens then circles around to give a near-360-degree view of the 100ft-high craggy ceilings. Later the camera swoops down to foot level, narrowly missing some inky puddles as it grazes the floor. It then continues to fly, revealing a small stream of water running through the cave down below.
Abandoned Britain: Haunting photographs capture the derelict churches, hotels and mansions left crumbling to dust
Peeled paint, crumbling brickwork and rotten timbers are a common theme in this striking photo series, which unearths abandoned buildings across the UK. Simon Yeung makes it his mission to highlight the beauty of decay through photography, capturing dilapidated train stations, hotels, churches, mansions and hospitals on his travels. He says he finds it 'tragic' how scores of buildings are left to crumble and rot, but he understands how the money needed to save them from peril is often too much. In a bid to get the desired shots, Yeung admits that he often puts himself in dangerous situations as he ventures into structures on the verge of collapse.
