The Cas­tle Gar­dens kiosk or Cas­tle gar­den palace (for­mer­ly known as Cas­tle Gar­dens Casi­no) was built as Buda Roy­al Palace gar­dens sur­round­ing the clo­sure, simul­ta­ne­ous­ly with the Cas­tle Gar­den bazaar. This is a neo-Renais­­sance build­ing. Since 2008, used for events. Cas­tle Gar­den Kiosk build­ing was built an engine room for the water sup­ply sys­tem of the Roy­al Palace. This is an eclec­tic build­ing, built in Renais­sance and Baroque styles. The deli­cious work of sculp­tor did the SchrAf­fl broth­ers (George and Armin). The grotesque murals are Robert Scholtz works, did these by ‘sgraf­fi­to tech­nique’. The north­ern part along the Danube Riv­er (today’s recep­tion) is a cof­fee house with Flo­ren­tine Renais­sance style cita­tions. On the south­ern part (a great room with vault­ed hall) were the Machin­ery instal­la­tions of water­works. Above the engine room (the gallery) was the engi­neer’s apart­ment. A tow­er build­ing stands between the two parts, which hid the chim­ney of steam boil­ers.
