Király Thermal Bath, Ottoman thermal bath in Budapest, Hungary.
Király Thermal Bath is an Ottoman-era thermal facility in Budapest featuring multiple pools at varying temperatures. The centerpiece is an octagonal pool beneath a domed ceiling with glass openings that allow natural light into the underground space.
Built in 1565 during Ottoman occupation, this bath served as a strategic facility to ensure water access remained available even during potential sieges. Its role in providing essential services made it an important piece of infrastructure throughout the decades of occupation.
The name Király ("King") comes from the König family, who bought the bath in 1796; Hungarians also call it Arszlán pasa fürdője after Arslan Pasha, who began it. The octagonal pool under the Turkish dome and the steam chambers keep the hammam layout. The bath has been closed since 2020 for renovation.
The facility has been undergoing major renovation work since 2020 and remains closed to visitors, with work expected to continue for some time. Check current opening status before visiting to confirm when it becomes accessible again.
The pools are fed by springs near the Lukács Baths, and under Ottoman rule the hot water ran to the site by gravity through channels made of larch wood. Today it arrives through closed pipes. The bath's octagonal pool and Turkish dome survive from the original hammam.
