Often dubbed 'the world's only seven-star hotel' (erroneously, as official rankings stop at five), the Burj Al Arab is one of Dubai’s most iconic structures, and goes a long way to earning its nickname. Resembling a billowing ship's sail, it stands proudly just off the Dubai shoreline and is best seen from Jumeirah Beach at sunset, when the skies turn all shades of pink and orange.
Once inside, the hotel is unquestionably at the high end of high-end. Michelin-starred restaurant Al Muntaha peers out from the 27th floor, offering gloriously panoramic dining, while the award-winning spa has infinity pools to spare. Aesthetically, it's a little more divisive: with gaudy colours and clashing patterns throughout, it has been described as ugly by some visitors.

Designed by famous Canadian-American architect Frank Gehry, the Guggenheim Bilbao is an artwork in its own right. The sculpture-like structure boasts titanium-clad curves designed to catch the light in different ways as the day progresses, and has been continually hailed as one of the greatest buildings of our time.
The interior is equally undulating and is centred on a large, light-filled atrium which has gorgeous views out over the river and the countryside beyond. There's also the small matter of the gallery's world-class modern art collection, from meditative Rothkos to Puppy by Jeff Koons, the largest flower sculpture on Earth. Visit in summer for the best light, and admire the beautiful exterior when the sun is low in the sky.
Dedicated to his late wife, Shah Jahan’s Taj Mahal is beautiful not only for its mesmerising marble facade. Their love story is one of bittersweet tragedy: Mumtaz Mahal ('the Jewel of the Palace') died while giving birth to their 14th child, so the emperor vowed never to marry again and promised he would build her the finest mausoleum ever seen.
It took around 20,000 workmen approximately 20 years to build the Taj Mahal, with the last marble slab finally laid in 1648. An urban legend holds that Shah Jahan was so determined that no future monument should ever rival the mausoleum's beauty, that he removed the hands of every single one of the labourers that toiled at the site. Visit in the relatively quiet early hours, when the building takes on a pink hue.
London’s St Pancras Renaissance Hotel is one of the grandest buildings in the capital. The enormous red-brick Gothic-Revival construction first opened in 1873 as the Grand Midland Hotel, and was described by poet Sir John Betjeman as "too beautiful and too romantic to survive" in the modern era of tower blocks, car parks and concrete.
He was almost right, as the original hotel closed in 1935 and only narrowly avoided demolition. After extensive renovation the building reopened in 2011 as the five-star St Pancras Renaissance Hotel. Conjoined with St Pancras railway station, you can enjoy its dramatic exterior from the other side of the Euston Road or lap up its luxurious interiors in a suite or at the Booking Office 1869 bar and restaurant.
Just an hour from Lisbon lies one of Portugal’s – and indeed the world's – most colourful palaces. This gorgeous hilltop complex was built in the 19th century on the ruins of an old monastery by King Ferdinand II as a summer palace for the royal family. It showcases an eclectic mix of architectural styles, from Neo-Gothic to Neo-Islamic.
Most of all, the palace was grand and romantic, and was described as "the most beautiful thing I've ever seen" by composer Richard Strauss. It was turned into a museum after the abolition of the monarchy in 1910, and the last queen of Portugal spent her last night there before going into exile. Get the best views from the nearby Castle of the Moors or the peak of Sintra Hill before exploring its opulent interior.
Probably the most famous castle in the world, Neuschwanstein is about as fairy-tale as it gets. But it wasn't built in the Middle Ages – instead it was constructed in the 19th century to deliberately resemble the towering fortresses of years gone by. Adorning a steep hill in southwest Bavaria, Germany, the spectacular structure inspired the design of the castle in Disney's Sleeping Beauty.
Inside, opulence abounds throughout its many rooms and music halls. Some are carved from wood, while others are painted with colourful murals. The best view of its exterior is from the Queen Mary’s Bridge in Marienbrucke, and, if you want to avoid the crowds inside, take the last tour of the day when most visitors have left.
It’s not the tallest building in New York City, nor is it the most famous, but the Flatiron building in Manhattan is definitely among the city's most striking. A triangular, 22-storey office block that looks almost two-dimensional when viewed from the side, the building was constructed in the Beaux-Arts style and measures just six feet (2m) across at its narrower end.
Built in 1902 at an astounding rate of one floor per week (once the foundations were laid), it was originally despised by the New York media and deemed the latest monstrosity from the city’s out-of-control construction business. Today, it’s one of the most-photographed landmarks in the Big Apple, and has developed into a beloved symbol of the city.
Thailand is dotted with incredible temples, but none are so stunning as Wat Rong Khun. This entirely white temple is a modern reconstruction of an older temple that was left to ruin. Unusually, it’s privately owned and is more of an artwork than religious place. Work is still being done on the temple, which is not expected to be fully finished until 2070 or beyond.
Full of dark symbolism, as you enter the temple a sea of grappling white hands representing human desire reach up from the floor, and its interior walls are decorated with politically motivated murals depicting demons and Western idols including Michael Jackson, the Terminator and Superman. Visit early in the morning to avoid the inevitable crowds.
Still under construction – it's finally slated for completion in 2026 – Gaudi’s most celebrated work nevertheless draws millions of visitors to experience its grandeur every year. The elaborate building’s most impressive part is its dramatic Nativity facade, which was created under the personal supervision of Gaudi himself and boasts thousands of intricate carvings related to the birth of Christ.
The interior is equally mind-boggling, as traditional cathedral architecture takes a backseat in favour of undulating curves inspired by nature. Columns resembling tree trunks sprout from across the cathedral floor, which branch into intricate vaults often adorned with vibrant glass. The ceiling is often cited as the building's most impressive feature, and the first thing many visitors do after entering is look up.
The second tallest building in Iceland, the Hallgrimskirkja church towers over this mostly low-rise capital city. It took 41 years to build and its design is inspired by the natural shapes and forms created by thick lava when it cools. Named after poet and national treasure Hallgrimur Petursson, the church was inaugurated in 1986 – the 200th anniversary of Reykjavik's city status.
Rising into the sky like two lines on a graph, the church boasts a sparse beauty and looks almost ominous when night falls. The sci-fi vibe continues into the interior, which is an eerie but appealing minimalist white throughout. See it at its most ethereal at sunrise or sunset, and don’t miss the view from the clock tower.
One of the world’s most precariously placed monasteries, Paro Taktsang (better known as the Tiger’s Nest) perches tentatively on a cliffside in the upper Paro valley in Bhutan. The elegant structure is built around a cave in the cliff face that is said to have been used by Guru Padmasambhava for meditation in the 8th century. Legend has it that he flew to the cave on the back of a female tiger.
Today the sacred site is a must-see for more intrepid travellers – and it makes you work for it. High in the Himalayas – 10,240 feet (3,120m) high, to be exact – the monastery is only accessible on foot via a four-and-a-half-mile (7km) uphill hike, though you can take a pony to the cafeteria en route, which has the best views of the complex and valley.
A breathtaking stalwart of the Milan skyline, the Duomo’s history spans more than six centuries of worship. The cathedral’s construction began back in 1386 at the peak of Gothic design, but was not truly completed until the mid-20th century. Over the decades, a succession of Italy's greatest architects, engineers and artists worked on the magnificent structure. Even Leonardo Da Vinci sketched some designs for a proposed domed tower, though they never made it off his drawing board.
Fabulously elaborate, the Duomo remains the fifth-largest church on Earth and is adorned with an astonishing 3,400 gargoyles and statues. If you're looking to avoid the crowds then your best bet is to go in the early morning or on a weekday, when the cathedral is at its quietest. Or stop by at sunset to see the iconic spires against the backdrop of the beautiful Italian dusk.
One of the world’s most famous landmarks, the Palace of Versailles, a UNESCO World Heritage Site, draws hundreds of thousands of visitors every year to experience its notorious opulence and luxury. There's a tremendous amount to explore, from the sumptuous Hall of Mirrors to the enormous landscaped garden estate, so you’ll want to plan your visit carefully.
Initially a royal hunting lodge, Versailles was turned into the palace we see today by the titanic figure of Louis XIV. Nicknamed 'the Sun King', Louis's extraordinary 72-year-and-110-day reign makes him history's longest-serving monarch, and Versailles benefitted hugely from decades of patronage. By the time of his death in 1715, the still-unfinished Palace of Versailles was already perhaps the grandest palace of its age.
Eight stories high, this vivid reconstruction still soars above the skyscraper-lined streets of Osaka – a collage of faded-green roof tiles, whitewashed triangles and golden lining. First built in the 16th century, the structure marked the pinnacle of Japanese castle-building until it was struck by lightning and burned to cinders in 1665. The modern castle was rebuilt in 1931.
Now a museum as much as a fortress, the castle looks particularly splendid at night, when upturned spotlights see its walls shine brightly against the dark sky. Surrounding the keep is a series of defensive structures, and the site's two-and-a-half million annual tourists can wander among turrets, baileys, gatehouses and walls. May is peak season in Osaka, so visit in autumn for still-pretty-good weather and fewer crowds.
There are two very distinct ways to experience Mont Saint Michel, a stunning abbey perched atop a tiny island on a bay in northwest France that's split between Normandy and Brittany. First, you could visit at high tide, when the delightfully symmetrical structure is reflected dreamily in the surrounding sea. Second, you could visit at low tide, when the island is surrounded instead by an ocean of sand.
The island is still reachable at high tide thanks to a causeway unveiled in 2014, while low-tide visitors should be wary of wandering the sands – the tides come in very rapidly and there are quicksand dangers, so avoid the bay unless you're with an experienced guide. Legend has it that the abbey was built in AD 708 on the orders of the archangel Michael, and it became a centre of pilgrimage and learning in the Middle Ages.
