What makes the hotel Palacio de Sal, located in southern Bolivia, special and unique is that it was built using salt instead of bricks and concrete

More than a million salt blocks, sourced from the world’s largest salt flat, Salar de Uyuni, form the foundation of this hotel. As a side effect, the hotel needs to be regularly restored because about 10% of it is lost every year due to rain.

The 4,500-square-meter hotel features salt-made artworks, a saltwater pool, a sauna, a terrace offering the opportunity to gaze at the unique sky of Salar de Uyuni, and a restaurant where you can enjoy traditional Bolivian cuisine.

In this hotel, where the floors, walls, roof, and furniture—basically everything—is made from salt, the cost of staying for one night ranges from 200 to 400 euros per room.
