The commune has maintained a European partnership with 5 towns for over 60 years.
Indeed, Mondorf-les-Bains is twinned since 1956 with : Bad Homburg (Germany), Cabourg (France), Chur (Switzerland), Mayrhofen (Austria), Terracina (Italy) and since 2018 Vale de Cambra (Portugal)
By maintaining regular exchanges, Mondorf-les-Bains manages to maintain its image outside the Grand Duchy, both in terms of tourism and socio-cultural activities.
