Palacio de Sal
Located on the edge of Salar de Uyuni, the world's largest slat flat, is a hotel built of salt blocks. The Palacio de Sal (Spanish for Palace of Salt) was first built in 1995 and soon became a populat tourist attraction.
However, mismanagement caused serioys environmental pollution and the hotel had to be dismantled in 2002. In 2007 it was rebuilt in a different location on the salt flat.
The hotel is made up of around 1 million blocks of salt, which are used for the floor, walls, ceiling and furniture (including beds, tables and chairs).
