Towers that seem alive, twisting and dancing with each other. An alien-like blob that looks like a UFO after dark. A building that’s literally a blur. All of these and more are homes, hotels, museums and cathedrals around the world created without any sense of restraint or desire to fit in. To say these bizarre buildings are unconventional would be putting it mildly – they’re almost too strange to be real.

The Tianzi Hotel, China

Could this be the weirdest-looking hotel in the world? Ten stories tall, the Tianzi Hotel in Hebei Province, China holds the world record for the world’s “biggest image building”. The three figures that make up its hulking shape are Fu Lu Shou – good fortune, prosperity and longevity.

Nautilus House, Mexico

Fanciful and strange, the shell-shaped Nautilus House in Mexico City hardly looks like a home. But even though the inside is just as unconventional as the outside – with carpets of plants, stone walkways and entirely curvilinear surfaces – a couple and their young children actually live there.

Atomium, Belgium

The aptly named Atomium building consists of nine interconnected steel spheres that together form the atomic crystal structure of iron (magnified 165 million times, natch). Designed for the 1958 World Fair in Brussels, this 335-foot-tall wonder contains exhibition spaces, a restaurant and a dormitory for visiting schoolchildren with escalators connecting the spheres.

Cathedral of Brasilia, Brazil

From the outside, this bizarre building hardly looks like a cathedral – but that’s exactly what it is, and once you step inside the beautiful and colorful stained glass affirms its identity. The Cathedral of Brasilia is made up of 16 curving concrete columns with glass in between them, and a glass ceiling.

Errante Guest House, Chile

The word ‘unusual’ doesn’t quite cut it when describing this extremely odd building, which hardly looks habitable with its sloping surfaces. Details on this structure are fuzzy, but it’s certainly an eye-catcher.

Kunsthaus, Austria

Called the “Friendly Alien” by its creators, Peter Cook and Colin Fournier, the Kunsthaus Graz is an art museum in Graz, Austria built in 2003 for the European Capital of Culture celebrations. The blob-like structure definitely deviates from the typical minimalist style of modern art museums and at night, when it’s lit up, it looks unlike anything else in the world.

Blur Building, Switzerland

From afar, it looks like little more than a strangely earthbound cloud. But get a little closer and you realize that it’s actually a building shrouded in man-made fog. The Blur Building in Switzerland is a suspended platform that sprays tiny drops of lake water into the air from 31,400 jets, creating the mist effect. The building was created for the sixth annual Swiss National Exhibition and can host up to 400 visitors at a time.

Tenerife Concert Hall, Spain

Who else but Santiago Calatrava could have created this sculptural work of art, the Tenerife Concert Hall in the Canary Islands of Spain? The dramatic curve of its sweeping roof gives it an entirely unique silhouette, especially when viewed from the side. Made from concrete, the auditorium connects the city of Tenerife with the ocean.

Kettle House, Texas

Made of steel sometime in the 1950s, the ‘Kettle House’ in Texas has attracted many a curious tourist. The unusual choice in materials and shape was probably influenced by the owner’s previous occupation – building storage tanks for oil companies.

Casa Batllo, Spain

One of Barcelona’s treasured buildings designed by the famed Antoni Gaudi, Casa Batllo is known locally as the ‘House of Bones’ for its flowing, skeletal stonework. With small balconies that resemble the faces of lizards and an exterior texture reminiscent of scales, perhaps it could more accurately be called reptilian.

Olympic Stadium, Quebec

Built for the 1976 Summer Olympics, the Olympic Stadium in Montreal is now used as a stadium for the city’s professional baseball and football teams. Its centerpiece is the Pisa-like leaning tower, the tallest inclined tower in the world at nearly 575 feet.

Guggenheim Museum, Spain

Considered one of architect Frank Gehry’s greatest works, the Guggenheim Museum in Bilbao, Spain is a mass of random curves made from titanium, which resemble fish scales. Gehry says “the randomness of the curves are designed to catch the light”, and that they do, with a brilliant shimmer that reflects the sparkling water of the Nervion River.

Kansas City Library, Missouri

What could be more appropriate for a library design than making it look like books on a shelf? The Kansas City Library in Missouri features a façade of book spines, including Tolkein’s Lord of the Rings and Shakespeare’s Romeo and Juliet, that fence in the parking areas which sandwich the historic building.

Federation Square, Australia

Taking up an entire city block, Federation Square is an imposing collection of architecture, but there’s more than enough whimsy to balance out its sheer size. Reminiscent of Gehry’s Guggenheim Bilbao – albeit far more geometric – this building’s design was the winner of an international competition to create a new civic precinct in the center of Melbourne, Australia.

Dancing Building, Prague

Hmm, what super-famous architect could have been involved in this building? That’s right, Frank Gehry had a hand in the design of the Nationale-Nederlanden building in downtown Prague, Czech Republic, which was co-designed by Vlado Miluni?. The building’s two main structures resemble a pair of dancers, hence its nickname – but it’s also known as ‘Drunk House’.

Cubic Houses, Netherlands

After many Rotterdam buildings were destroyed in WWII, architects had a bit of fun redesigning many areas in new, modern and sometimes surprising styles. The Cubic Houses are one example, designed in the 1980s by architect Blom. They’re basically standard houses turned on a 45 degree angle, each resting on a hexagonal pylon. The cubes are so fascinating that one owner decided to buy and manage a “show cube” to keep tourists from disturbing the rest of the residents.
