Széchenyi is the largest medicinal bath in Europe and one of Budapest's most iconic landmarks. Built in 1913 in the neo-baroque style, the grand yellow palace houses 18 pools — three outdoor and 15 indoor — fed by two thermal springs reaching 74–77°C. The mineral-rich waters are recommended for joint problems, rheumatism, orthopaedic conditions, and traumatology. The outdoor pools remain open year-round, creating the famous spectacle of bathers playing chess in steaming water during winter. The complex includes a full range of wellness services: Finnish saunas, steam cabins, massage treatments, and a salt chamber. Tickets can be purchased online or at the door. Locker rooms, towel rental, and swimwear are all available on site.
