Constructed in 1899, the building was designed by a well-known architect named Grosser. The Spa House in Świeradow-Zdrój is divided into two buildings connected by the longest larch Promenade Hall (Hala Spacerowa) in Lower Silesia with a length of 80m, which houses a drinking water spring. Next to the building are terraces and the Artificial Grotto, which once housed a pump room for mineral waters. It is also the starting point of the M. Orłowicz Main Sudeten Trail. The basement of the Spa House accommodates the Spa Museum (Museum of Spa Mining) established to commemorate the 260th anniversary of the building of Świeradów's first mineral water springs.
