In Tuscany, between the delightful Lucca and Pistoia and not far from Florence, Montecatini Terme is the 56th Italian site to be declared a UNESCO World Heritage Site. With its Art Nouveau and neo-Gothic architecture, Montecatini Terme has managed to rise to the Olympus of the "Great Spa Towns of Europe" because of its past and its incredible features.

As of 2021, 11 cities, spread over 7 countries, are part of the shortlist of UNESCO of the "Great SpaTowns of Europe". They are Baden bei Wien in Austria, Spa in Belgium, the three cities of Karlovy Vary, Františkovy Lázně and Mariánské Lázně in the Czech Republic. But also the famous city of Vichy in France, Bad Ems, Baden-Baden and Bad Kissingen in Germany, and Bath in the United Kingdom. Montecatini Terme in Italy completes this great list.
