Experts consider it one of the most important European industrial monuments, corresponding to the ones in Sardinia (Italy), Mancha (Spain), Indra (Slovenia), Ruhr (Germany), Le Creusset (France) and the Iron Bridge (Great Britain). It was made by the German company "Minengeselischaft Fr. Spidel" in 1903. During the First World War, in 1916, the premises were occupied by French troops so a part of it was destroyed. In 1925 the new company that managed the premises restored and expanded the factory. In the period of 1933-1936 the factory was reopened and then again between 1950-1962 under new administration. In 1963 the facilities were granted to the Greek Ministry of Industry and it has been inactive thereafter. Based on modern scientific standards and by examining its integrity, authenticity and uniqueness, it is a monument worth preserving.
