Palacio de Sal

[2] It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes at an altitude of 3,656 meters (11,995 feet).

Salar de Uyuni has long attracted tourists, who came great distances and needed a place to rest before returning to their cities.

Therefore, it was logical to erect a hotel made of salt, which is in ready supply at Salar de Uyuni.

The first hotel was built in 1993–1995[3][4] out of salt blocks in the middle of the Salar de Uyuni,[5][6] and soon became a popular tourist destination.

The building was constructed of about 1 million 35-cm (14-inch) salt blocks, which are used for the floor, walls, ceiling and furniture, including beds, tables, chairs and sculptures.
