The European Historic Thermal Towns Association (EHTTA), is a membership organization representing historic thermal spa towns and regions across Europe.
The EHTTA was founded in 2009 in Brussels (Belgium) by six Founder Members - Acqui Terme (Italy), Bath (UK), Ourense (Spain), Salsomaggiore Terme (Italy), Spa (Belgium), and Vichy (France). Many of these towns were involved in the 3-year long co-operation project called “Thermae Europae” (Culture 2000 Programme) which aimed to valorise and preserve thermal cultural heritage in Europe, and were keen to continue working together by establishing a permanent network.
As a result, EHTTA was established as a non-profit association based on the need to encourage, protect and enhance thermal, artistic and cultural heritage throughout Europe.
In 2010 it was certified as a Cultural Route of the Council of Europe, one of 48 across Europe (in spring 2023).

Associations or regions providing their commitment to support the aims of EHTTA and the Cultural Route.
Reserved for thermal towns outside of Europe which can document the historical relation with European thermal heritage.
