While thermal baths have been part of the city’s culture since the Romans, the oldest still in use were built by the Ottomans. In the early 20th century, Budapest saw a renaissance in its spa culture. The Széchenyi Baths, up in City Park, not only present a wonderland of curative waters and therapies, but it’s also a prime architectural example from early 20th century Budapest. Characterised by their neo-Baroque design and yellow façade set against the blue hue of the pools, architect Imre Francsek designed this 1920s “lido” that soon became an icon of Budapest spa culture.
