Few people haven’t heard about the ancient city of Persepolis, which lies at the foot of the Mountain of Mercy (Kuh-I-Rahmat). In ancient times, Persepolis was the capital of the Achaemenid Empire. Regretfully, it was burned by the Greeks in 330 BC after they looted the immense treasure of this city. It is said that Greeks needed 5,000 camels and 20,000 mules to carry all the treasures from Persepolis. The only thing of Persepolis that has survived the wear of time is the ginormous stone terrace 530 by 330 meters adorned by elaborate stone sculptures. It is amazing how intricately detailed some of the sculptures are, despite the fact that they were created many centuries ago.

Located at La Casa Del Arbol or “The Treehouse” in Baños, Ecuador, this small house was built for the stunning view on the Tungurahua Volcano it offers. But the real attraction is the swing attached to one of the tree's branches. It is far from your average swing, and it is surnamed the "Swing at the End of the World" for a good reason. Located off a giant cliff at over 2,600 meters above sea level and with absolutely no safety features, this swing promises a serious thrill to whoever is brave enough to ride it.

Italian architect Giovanni Pesamosca’s work is reaching scenic new heights. His cabin is perched on the edge of Foronon Buinz in Italy’s Julian Alps. The pre fabricated structure was placed at the spectacular location in memory of deceased climber Luka Vuerich, and is now providing free accommodation complete with jaw dropping panoramic views for up to nine people… the intrepid kind willing to make a long trek to 8303 feet (2531 meters) above sea level.

The Ring of Life is a 515-foot (approximately 157 meters) landmark built in the city of Fushun, China. The landmark is built with an observation deck accessible by elevator, as well as 12,000 LED lights. Having abandoned local entertainment projects due to the small local population, urban planners settled on building a sightseeing landmark instead in order to attract a tourist industry to the region. The structure uses approximately 3,000 tons of steel and cost an estimated $16M U.S. dollars.
