If you and your significant other are architecture buffs, it stands to reason that you might want your proposal to occur in the shadow of a landmark structure. But such a feat is trickier than it may seem: The crowds atop the Burj Khalifa or World Trade Center prevent any chance for romance; the Eiffel Tower and Trevi Fountain are too cliché; and, unless you can convince an especially romantic homeowner, private residences are out of the question for obvious reasons. But fear not: AD has rounded up some of the world's best architectural landmarks, sites that are both breathtaking and romantic—and offer some semblance of seclusion. Click through to see our selection, then get to work picking out the perfect ring.
Villa Savoye, France
Located a short train ride from Paris, Le Corbusier and Pierre Jeanneret's iconic building is often overlooked by tourists who stay within city limits. Its pillared overhang offers the perfect shaded spot for a romantic moment.
Versailles, France
Wander away from the Marble Court and Hall of Mirrors and explore the vast gardens surrounding the iconic French château. Boats and tandem bicycles are available for rent to help reach the ideal secluded spot.
Park Güell, Barcelona
Save the popular (and ever-crowded) Sagrada Familia for another day and explore the winding pathways and enchanting architecture of Gaudí's impressive park, which offers panoramic views of Barcelona.
The Forbidden City, Beijing
The massive walled compound, which once served as the Chinese Imperial Palace, is a UNESCO World Heritage site and comprises over 980 buildings, leaving plenty of room for a sentimental stroll.
The Glass House, New Canaan, Connecticut
Nestled in the woodlands of Connecticut, Johnson's famous glass structure has a striking presence in any season. While the main building is the property's most famous, several outbuildings of varying styles dot the property, making it a veritable architectural treasure trove.
Notre Dame de Paris
Forget climbing to the top of Paris's famed cathedral: Wander around the east side for an unusual view and quiet gardens, and then venture toward the quaint streets of the adjacent Île Saint-Louis.
Villa Borghese, Rome
Atop Rome's famed Spanish Steps, the expansive garden comprises several structures, including the main villa, which was designed by Giovanni Vasanzio, and a meandering maze of flora.
The London Eye
If you're a lover of London but want a little privacy, rent out a private capsule in the city's giant Ferris wheel. With the Cupid's Capsule package ($480), you can take in expansive views while sipping Champagne and tasting chocolate.
Burj Al Arab, Dubai
If you're really looking to go all out, land your chopper on the private helipad at Dubai's landmark, sail-shaped building. Once you've popped the question, celebrate inside at the world's only seven-star hotel.
