The original 17th-century Baroque summer palace was a formal mansion and even witnessed the imperial coronation celebration of Emperor Franz I. A restaurant has operated in the unique historical space since the 1920s. The last tenant was Václav Šlechta, who ran the eponymous restaurant until World War II began. After the war, the restaurant was nationalized, and in the 1960s, nearly in ruins, it was closed for good. This popular destination is now under renovation.
