The Gellért Thermal Bath and Hotel is the most architecturally distinguished of Budapest's great spa complexes — a monumental Art Nouveau building whose interior features a soaring indoor main pool with arched glass roof, ornate tilework, and Roman columns. Built between 1912 and 1918 at the foot of Gellért Hill on the Buda side of the Danube, the facility draws water from the same spring system that has served bathers in this location since Turkish occupation in the 16th century. The outdoor pools include a wave pool, terraced sun decks, and views across the Danube towards the Pest skyline. The Gellért has long attracted artists, intellectuals, and heads of state, and its grand interiors are considered among the finest examples of Hungarian Secession architecture.

The Gellért springs were used by the medieval Hungarian Kingdom and subsequently by the Ottoman Turkish administration that occupied Buda from 1541 to 1686. The current building was the result of a major civic effort to create a spa complex worthy of Budapest's ambitions as a great European city at the turn of the 20th century.
Gellért is as much cultural monument as thermal facility — its interior has appeared in countless films, artworks, and literary references. The grand main pool, with its steam rising to the vaulted glass ceiling, is one of the defining images of Budapest. Visiting the Gellért is considered a near-essential part of experiencing the Hungarian capital.
Budapest's thermal springs are among the most productive in Europe, with natural flow sufficient to supply multiple large spa complexes without pumping. The Gellért has undergone major renovation cycles to modernise its systems while preserving its historic architectural fabric.
