The National Historical Museum belongs to The Historical and Ethnological Society of Greece (HESG), which was founded in 1882 for the purpose of collecting, saving and presenting relics and documentary evidence relating to modern Greek history. It is the oldest museum of its kind and it includes rich collections, which highlight the most representative phases of Neo-Hellenism, from the fall of Constantinople (15th Century) on. The National Historical Museum is also a research centre for Modern Greek History.
