The practice of travelling for health and medical reasons has a long history. Even the ancient civilizations recognized the therapeutic effects of mineral thermal springs and sacred temple baths. For example, the Sumerians constructed health complexes around hot springs more than four thousand years ago, which included temples with flowing pools.
Ancient Romans built resorts with thermal health spas, and therapeutic temples thrived during the Greek domain. Ancient Greeks were known for their travels to the sanctuary of the healing god, Asklepios, believed to reveal remedies for different ailments in the dreams. This sanctuary was in fact a small territory in the Saronic Gulf named Epidauria – today considered as the birthplace of medical tourism as we know it.
