10-storey slide in City Museum (St. Louis/ Missouri)

St. Louis City Museum consists largely of repurposed architectural and industrial objects.
One of the most popular attractions are the Enchanted Caves and Shoe Shafts that run through the center of the Museum, all the way to the 10th floor.
In the Enchanted Caves, guests will find an elaborate cave system hand-sculpted by Bob Cassilly and his crew. From every direction, a different creature is staring back.

The Shoe Shafts were left over from when the building was the International Shoe distribution building. To get the shoes from floor to floor, staff would place the shoes on the spiral shafts that would lead down to the loading dock. When the caves originally opened up in 2003, there was only one spiral shoe slide that was three stories tall, but in 2008 a second one was opened, that starts at the roof and goes down to the caves' entrance.

The Bund Sightseeing Tunnel (Shanghai/ China)

Originally planned to be a moving walkway, this tunnel turned into one of Shanghai's strangest tourist atrractions. Bizarre, trippy audio-visual effects play as you travel in an automated car under the Huangpu river.
‘The story is about going from space into the core of the Earth and out again. We couldn’t show the dirty Huangpu, which has no fish, so we went for something bigger and better. It’s the only tunnel like it in the world.’

It runs from The Bund to Lujiazui, close to the Pearl Tower and costs 55RMB for a round-trip. Open from 8am-10pm daily.

Tenerife Concert Hall (Santa Cruz/ Spain)

The Auditorio de Tenerife is located on the waterfront in the Los Llanos are of Santa Cruz, the capital of Tenerife. Situated between the Marine Park and the edge of the port, the auditorium connects the city to the ocean and creates a significant urban landmark.
The all-concrete building is characterized by the dramatic sweep of its roof. Rising off the base like a crashing wave, the roof soars to a height of 58 meters over the main auditorium before curving downward and narrowing to a point.

The Blur Building (Yverdon-les-Bains/ Switzerland)

The Blur Building was constructed in 2002 for a Swiss Expo. The primary construction material is water, pumped up from the lake below and emitted into the air by over 30,000 high pressure nozzles. Once inside, the low hum of the nozzles emitting the water vapor into the air blocks out all sound from the outside and visitors are left with a sense of nothingness.

Homeless Experience Hotel (Göteborg/ Sweden)

Faktum Hotels in Göteborg, Sweden has no rooms, but offers places to sleep that the city’s homeless might also use.

You can book a ‘room’ on their website and be led to a popular spot for the homeless somewhere in the city, such as under a bridge, in a derelict factory or on a public bench. Booking costs €10 a night and it's up to you to really stay in the booked ‘room’.
Proceeds go towards the Swedish charity magazine Faktum who wants to raise awareness for the large group of homeless people in Göteborg, many of which have to sleep under the sky even in scandinavian winters.

The Neverwas Haul (Vallejo/ California)

The Neverwas Haul is a 3-storey Victorian House on wheels, built in 2006 by Major Catastrophe (Shannon O’Hare) and a crew of 12, made from 75% recycled materials. “After building the Clocktower in ’05, we were sitting in camp at Burning Man talking about our adventure so far. I thought how much we looked like some explorer’s club from some Victorian sci-fi, then I went further and drew the first Neverwas Haul concept sketch of an explorer’s club that really explores. I also got inspired by the book Snowcrash – there is a brief note about a Victorian house on tank treads in it.”

Every year for the Burning Man Festival the Neverhaul leaves the San Francisco Bay Area on a trailer for Black Rock City, Nevada. Once out on the desert lake bed which locals call the “playa,” the Neverwas Haul roams freely, a steampunk masterpiece brought to life with a diesel engine and a wooden ship’s wheel.
