A wooden building in the Swiss Style was finished in 1993 as a replica of the original Market Colonnade by architects Fellner and Helmer from 1883.The original one was built as a makeshift in place of the old Carlsbad town hall from 1520.The Spring of Charles IV springs in The Market Colonnade under a metal relief with motive of the Spring Discovery. Charles IV, the founder of the town, healed his injuries in the local spring called Glutton (_rout, or Fresser) and thank heavens the healing was successful. The remnants of the spring pool are still evident in the Colonnade underground.
