The Great Spa Towns of Europe is a transnational World Heritage Site consisting of a selection of 11 spa towns across seven European countries. They were developed around natural mineral water springs.^[1][2] From the early 18th century to the 1930s, Western Europe experienced an increase in spa and bathing culture, leading to the construction of elaborate bath houses.^[1] These would often include gardens, casinos, theatres, and villas surrounding the springs and the bath houses.^[1][3]

The city of Bath was originally inscribed on UNESCO's World Heritage List in 1987.^[4]

The efforts to get the Great Spas of Europe onto the World Heritage List began in 2012, and the nomination was submitted in 2019.^[5] On 24 July 2021, the Great Spas of Europe was officially inscribed on the World Heritage List.^[2]
