7. Meteora Monasteries, Greece
Built atop towering rock pillars in the 15th century, the Meteora (“hovering in the air” in Greek) Monasteries are one of the most important Eastern Orthodox monasteries in Greece. It wasn’t until a century ago that visitors could access the sacred structure through bridges and roads. Be extra cautious if you wish to enjoy the spectacle in person.

Puerta de Europa (”Gate of Europe” in Spanish) towers are two twin office buildings in Madrid. Completed in 1996, the buildings stand 374 feet high with a 15° incline towards each other. If you stand near the bottom of the buildings, you might get a feeling that they’re falling on top of you.
