After its reconstruction at the beginning of the 20th century, the Saalburg became an important archeological museum. The UNESCO World Heritage Day focuses on the early days of the Saalburg Museum. The visitors can meet people from this era and representatives of society, culture and the military.

In scenes with authentic contemporary witnesses, the former view of Roman heritage and cultural mediation is presented. The Musaion, an exhibition area presenting the turn-of-the-century collection around 1900, is also open to visitors on this day.
