If the best architecture aims at eternity, to paraphrase famed English architect Christopher Wren, then these new hotels are bound to be immortal. The 10 hotels on our list all opened within the last four years, and each is an example of awe-inspiring design in its own right. You can stay in a wave-like skyscraper in Chicago, a stack of cantilevered cubes in Portugal, or a hotel tucked into the wild cliffs of an Australian island. And, even better, it won't cost a fortune to spend a night in these architectural wonders. Six of the 10 are under $200 a night.
Yas Viceroy Hotel, Abu Dhabi, United Arab Emirates
This 499-room hotel was the first to be built straddling a Formula 1 racetrack (it opened in 2009 and was renovated in 2011 to become a Viceroy). The structure consists of a pair of 12-story towers joined by a sweeping, 700-foot curvilinear skin of glass and steel—actually 5,800 pivoting, diamond-shaped glass panels that reflect the sky by day and are illuminated up by an LED system at night. The architects' aim was to reflect artistry and geometries associated with ancient Islamic art and craft traditions, and from a distance the panels create the appearance of a spectacular veil. 888/622-4567, viceroyhotelsandresorts.com; from about $210 per night.
