The European Historic Thermal Towns Association (EHTTA), is a membership organization representing historic thermal spa towns 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 by the Council of Europe as a European Cultural Route, one of 40 across Europe.
EHTTA has grown from its original 6 Founder Members to a healthy non-profit association, a network of 49 members in 18 countries
We celebrate towns and territories which all have a rich historical and cultural heritage and use their thermal mineral waters for health and well-being.
EHTTA has different categories of membership:
Municipalities that fall into the strict definition of spa towns. They must comply with EHTTA’s criteria
Associations or regions providing their commitment to further 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
Member towns have to meet the following criteria:
