World's Most Unusual Hotels
Palacio de Sal, Uyuni, Bolivia
Hotels made with ice blocks are a dime a dozen, but salt blocks? Now, that’s unusual. But Palacio de Sal is no gimmick. Located in Salar de Uyuni, the world’s largest salt flat, this 16-bedroom hotel was built from the only construction material readily available. It’s an architectural embodiment of the environment. One million salt blocks measuring 14 inches were mortared together with salty water to construct everything—even the beds, chairs, and dry sauna. Just pray it doesn’t rain.
