Pink sand Santorini beaches are natural beaches that have a pink hue to their sand. This unique color is often due to the presence of crushed coral, shells, and calcium carbonate in the sand. Some famous pink sand beaches can be found in places like the Bahamas (e.g., Pink Sand Beach on Harbour Island), Bermuda (e.g., Horseshoe Bay Beach), and Greece (e.g., Elafonissi Beach).
Sanitoria, on the other hand, historically referred to health resorts or facilities where people would go for rest, relaxation, and recuperation. These were often associated with treatments for various health conditions, such as tuberculosis. However, the term "sanitorium" has become somewhat outdated, and modern healthcare facilities and treatments have largely replaced them.
