The New Seven Wonders of the World

The Great Wall of China runs more than 21,000 kilometers (over 13,000 miles), not as one continuous wall but rather as fortified wall sections. Some of the sections date back more than 2,500 years, though only 8.2 percent of the existing wall is original. The Mutianyu Great Wall is one of the more accessible portions. Hike (because that is what you’ll be doing, even on the wall itself) up the Great Wall, then slide down the side of the mountain on a toboggan. Alternatively, explore the Simatai Great Wall, which retains a more authentic feel—save, of course, for the fake water town at the bottom. Even more remote is the Jiankou section, which is largely unrestored, so book with an experienced group like Beijing Hikers or Wild Great Wall.

Petra flourished more than 2,000 years ago, trading with Rome as an equal before being abandoned after a series of earthquakes in the 4th and 6th centuries C.E. It wasn’t until the 19th century, when European explorers “rediscovered” it, that the ancient city returned to the public consciousness. Now, visitors can walk down the narrow canyon of the siq to the city entrance—as dramatic an approach as any to a tourist attraction on the planet. The canyon opens up onto the carved facade of the Treasury, Petra’s most iconic site. From there, you can explore the cliffside tombs with their colorful bands of sandstone, the Street of Facades, and the amphitheater hewn from living rock. The ancient center lies some distance off, along with the splendid old Monastery, which sits at the top of a steep but rewarding climb. Consider buying a three-day ticket and visiting at different times of day to enjoy the changing light—early in the morning is best for the Treasury, while late afternoon is better for the Royal Tombs.

This month marks the hundred-year-anniversary of the “re-discovery” of this Inca citadel by Hiram Bingham. Machu Picchu deserves its clichés--'place of a lifetime,’ ‘bucket-list destination’...'mystical’...'amazing’... Sometimes, it’s okay to simply stick with others’ adjectives; the thesaurus isn’t always a good thing. You’re not necessarily an ‘unoriginal tourist’ just because you agree with scores of published accounts that describe a site the same way. The distinctive trapezoidal windows of Inca construction almost always frame compelling views--the magic of stone. You’re in the heart of the Andes; for a moment, stop seeking words. Drink in the view.

A brilliant work of architecture and astronomy, the Pyramid of Kukulkán at Chichén Itzá is so precisely engineered that on the vernal and autumnal equinoxes, the sun casts shadows that slither like snakes and seem to descend the structure’s stairways. Said to represent the plumed-serpent deity Kukulkán, the shadows return to earth twice yearly to drink from sacred sinkholes known as cenotes. Today the phenomenon attracts thousands to the already crowded archaeological site, but almost-identical light-play can be seen the day before, alongside a mere fraction of the visitors.

No matter how many postcards you’ve seen of Rome’s iconic Colosseum, you just don’t get it until you pass beneath its crumbling arches. Built by Emperor Vespasian in 72 C.E., the huge amphitheater held 50,000 spectators and marked its opening with 100 days of brutal spectacles like gladiator combat and animal fights. The Colosseum was in use for four centuries, and now you can tour the ruins. Walk through the Hypogeum, an intricate series of tunnels and elevators originally used to transport animals, slaves, and gladiators, to the performance above, or take a moonlit tour to have one of the world’s most storied structures all to yourself.

The Taj Mahal is referred to as “the jewel of Muslim art in India,” by UNESCO in its listing on the World Heritage Site registry. The Mughal ruler Shah Jahan had the truly magnificent white marble mausoleum built in 1632–1648, in memory of his favorite wife, Mumtaz Mahal. For its construction, artisans from all over the empire, Central Asia, Iran, were summoned and the final result of their stonework, calligraphy, carvings, gardening, woodwork, and soaring domes remains one of the universally admired masterpieces of world heritage. Allot ample time to tour the site—besides the mausoleum, there is a mosque, a guest house, cloisters, courtyards, gates, and vast gardens. In addition to being stunningly beautiful from afar, the iconic site is evocatively romantic and up-close, the intricate details in its architecture, ornamentation, and history, are revealed.
