Mieczysław Radwan’s Museum of Ancient Metallurgy of the Świętokrzyski region in Nowa Słupia was opened to public on 29th May 1960.
It was an initiative of professor Kazimierz Bielenin and professor Mieczysław Radwan who discovered the ancient black metallurgy site in świętokrzyskie. The museum’s building was raised above relics of 45 furnaces found on an archaeological site called Nowa Słupia nr 2. The newly founded institution was a branch of the Museum of Technology in Warsaw.
The object was extended in 1967-1968 courtesy of Smeltery in Ostrowiec Świętokrzyski town. The museum was reopened on 9th June 1969 in a ceremony that also memorialized Mieczysław Radwan by adding his name to official name of the museum and commemorating him with a plate inside the building.
2016 was a breakthrough year in history of the museum. The Nowa Słupia municipality took over a charge of the institution. With help of EU funds a project started with the main aim of erecting a modern building and creating a multimedia exhibition.
Since 16th December 2021 the new facility is once again available for visitors.
