Another unique building is the Guggenheim museum in Bilbao, on the North of Spain. It has some art galleries inside and there is a statue of a dog outside. It is made of different materials. Enjoy the video!
What about staying in a hotel made of ice? It is possible if you travel to Sweden! The ice hotel has bedrooms, restaurants, etc. made of ice and snow. There isn't a swimming pool.
Finally, what about an spectacular view of the sea from the most luxurius hotel in the world, the 7 star Burj Al Arab hotel in Dubai?
